Hey guys, this is Ahnaf.

I have decided to chose water as my molecule.

Water molecule has a tetrahedral electronic geometry and V-shaped molecular geometry.

Water has an application to the daily aspects of our lives. From brushing teeth in the morning to cooking, drinking, watering plants, cleaning clothes and many many other applications.

That's all from me. Thanks ;)

Hi and Assalamualaikum to Dr.Ain and my friends.I am Nur Athirah Binti Mamat and i am interested in a compound called Trichlorofluoeomethane/CFCl3/CFC11 which was once widely used in manufacture of aerosol sprays,solvents and refrigerants.It has a molecular and electreonic geometry of tetrahedral.

When released to the environment,it can react with ozone layer,damage it and eventually release harmfull gases.

I am interested in this compound because i want to spread awareness that this compound should be fully banned because despite of its usefull properties in manufacturing sector,it has a big negative effect to global warming.
Thanks for reading and have a nice day.

Hi and assalamualaikum, my name is Siti Hajar and today I would like to share with you guys my chosen atomic molecular model wich is acetic acid. The acetic acid or also known as ethanoic acid, CH3COOH, have a molecular structure like a cute dog .  Acetic acid is also used for the treatment of outer ear infections like the growth of fungus and bacteria. Acetic acid is used in vinegar, which is used as a condiment & in the pickling of raw vegetables and other foods. Acetic acid is used for the manufacture of inks and dyes. So, I ended my short essay with a chemistry joke.

Q: What did the scientist say when he found 2 isotopes of helium?
A: HeHe

Assalamualaikum and hello my dearest friends.I am Aqilah. I chose the molecule NH3 or Ammonia. I think this molecule is very interesting because it consist of 3 bonding atoms and one lone pair at the central atom.The electronic geometry is tetrahedral while the molecular geometry is trigonal pyramidal. This molecule is essential for many biological processes and serves as a precursor for amino acid and nucleotide synthesis.

In the environment , ammonia is part of the nitrogen cycle and is produced in soil from bacterial processes. Ammonia is also produced naturally from decomposition of organic matter including plants , animals and animal wastes.

Ammonia is used in:
🌸 Agriculture as fertilizers which is about 80 % from the industries.
🌸 Refrigerant gas
🌸 Purification of water supplies
🌸 Manufacture of plastics
🌸 Manufacture of explosives
🌸 Manufacture of textiles
🌸 Manufacture of pesticides
🌸 Manufacture of dyes
And other chemicals...

It is found in many household and industrial-strenght cleaning solutions by adding ammonia gas to water.

Dr Ain.
My Name is Nur Alya binti Sharifuddin
My favourite molecule is Ethanoic Acid

In ethanoic acid CH3COOH, there are three interior atoms: two C and one O. We assign the molecular (and electron-domain) geometry about each interior atom separately: The geometry around the first C is tetrahedral. The geometry around the second C is trigonal planar.

The daily usage of ethanoic acid is as a raw material for making vinegar.

That is why I love ethanoic acid :)

Assalamualaikum and a very good day I wish to all of the readers especially Dr Ain Jamil. I'm Sham, so this is my favourite molecule model which we call it Ozone (O3). I want to say that this molecule is made up of three Oxygen atoms and this molecule contain a oxygen-oxygen single and also a oxygen-oxygen double bond. This polar molecule has a trigonal planar molecular geometry. In addition, this Ozone is a layer that covers the Earth means that, it is very important. We get protection from UV radiation as Ozone layer absorbs the radiation that emitted by the Sun.

Hello-mello from me everyone! My name is Syaz. Yesterday, during our lab session, we learnt about molecular shape of a molecule that were determined by VSEPR Theory. So here is my 'not-so-special' picture with my favourite molecule structure which is methane (CH4). As we know, this molecule is a hydrocarbon and is the simplest alkane. I chose this molecule because I think it has a unique shape which is 1 carbon as the central atom and 3 hydrogens as the terminal atoms. When I was constructing this hydrocarbon, there was a sudden flashback of a moment when I was in my secondary school, doing the same structure; but with my gegirls gang. Nostalgia right? Okay so before I end this caption, I would like to share fun facts about methane. It is the main constituent of natural gas. The relative abundance of methane on Earth makes it an attractive fuel, although capturing and storing it poses challenges due to its gaseous state under normal conditions for temperature and pressure. Attractive but dangerous? Nice. And do you know some lakes can 'burp' methane?

Assalamualaikum and a very good morning to Dr. Ain and my fellow classmate.My name is Nur Fazlie Bin Selamat. Yesterday I get a chance to build a molecule from the molecular kit that have been provided. I choose to build a propene molecule which is from the alkene group that only consist of combination between hydrogen atom with carbon atom.Propene only contain 3 carbon atom and this give the propene a non-polar molecule properties.For this propene molecule,it doesn't contain any lone pair and the shape is a little bit complex.Propene get the molecular shape from combination of 2 trigonal planar shape and 1 tetrahedral center. The first carbon atom form a single bond with two hydrogen while it's form a double bond with the second carbon atom. The second carbon atom form a single bond with one hydrogen and with the third carbon. The last carbon which is the third one form a single bond with three hydrogen. The first and second carbon atom form two trigonal planar while the third carbon form one tetrahedral. I like this molecule because of it's shape.Propene is the second most important starting product after ethene in petrochemical industry. It is the raw material for wide variety of products. Polypropene plastic uses include films, fibres , containers and packaging. Propene also used for the production of imp.

Hi everyone! It's me Aina. So i 've decided to choose ethylene as my favorite molecule and here is my selfie with it's 3D structure. I do think that this structure was so simple and cute. Ethylene is the simplest alkene example. The molecular geometry is trigonal planar. Two overlapping triangles present since each carbon is the center of planar triangle. Ethylene is a polar molecule but it is symmetrical. So it contains internal dipoles but contains no net dipole moment. Ethylene is the starting material for several industrial synthesis and also used in extraction of rubber.

Hi everyone, it's me Farahah. My favorite molecule that i found quite interesting is SF4. The sulfur in SF4 is in the formal +4 oxidation state. The structure of SF4 can be anticipated using the principles of VSEPR theory: it is a see-saw shape, with S as the central atom and contains one lone pair. This compound, in real life is a useful reagent for the preparation of organofluorine compounds, some of which are important in the pharmaceutical and specialty chemical industries.

Hello everyone, I am Yasmin and obviously im holding a Butane molecule. I chose butane for its nice shape and interesting characteristics. As we know, butane consists of 4 Carbon and 12 Hydrogen. 4 Carbon reminds me of getting cgpa 4 flat and I hope that it will come true. I believe that everyone want it too. For your information, Butanes are highly flammable, colorless, odorless, easily liquefied gases. Also, the name butane was derived by back from the name of butyric acid. The molecule is also symmetric that every atom has its pair, and of course no lone pairs is present. That whats make it amazing💐

ETHANE
This is Farah Dayana and I am a motivator @ psychologist to be. I am holding a structure of ethane, an organic molecular compound. One of ethane's application in daily life is it is used in the production of ethylene for making plastics, anti-freeze and detergents. Carbons are sp³-hybridized, meaning that both have four bonds arranged with tetrahedral geometry  If you ask me what I like from this structure, I would say "it is because this structure has great stability which motivates me to be a trustworthy person. Well... I think that's all. If i want to continue, it will be a long story that is not even worth to be your bedtime story. Bye~

Hello ,my name balqis.
Today i like to talk about SO3. While doing experience with molecular model i cant keep my eyes from SO3. This is because its have beautiful double bonding covalent between each 3 oxygen with sulfur. VSEPR notation of SO3 is AB3 and its electronpair geometry is trigonal planar same as its molecular geometry. As oxygen and sulphur share equally in the covalent bond and have symmetrical charge distribution so its polarity is non-polar. In daily life SO3 was use as essential reagent in sulfonation reactions.This process afford detergent, dyes,and pharmaceuticals.  I simply like SO3 because it have simple and beautiful bonding.

This compund is very interesting as it is made of Carbon as the central atom and Oxygen as the terminal atom. There are 1 carbon atom and 2 oxygen atom. The two elements are combined with double bond. Hence, it makes this molecule very unique and beautiful when constructed using the molecular model. Both electronic and molecular geometry of carbon dioxide is linear giving the bond angle 180. Carbon dioxide is a non-polar molecule. As we all know, carbon dioxide is used by plants to undergo photosynthesis while in iron extraction, the forming of carbon dioxide act as the main source of heat in the blast furnace.

Assalamualaikum dr ain. So here are one of my fav molecule that i like. It is SF6. The electronic geometrical is octahedral and the molecular geometrical is also octahedral. This is because it contain AB6 and do not have any lone pair. That is why the electronic geometrical and molecular is the same. So the reason i like it is all about the name of it which is octahedral. To me the name of it mean a lot to the molecule such as “octa” which mean 8 and “hedral” which is planes. So here it means it have 8 planes because it is like a 2 piramid upside and downside that have 4 planes each and when combine it will be 8 planes. It is true that also other molecule has a specific name that unique to itself but to me the most wonderful meaning is octahedral.

Hi everyone! So, yesterday, I built a model of butene, C4H8, using the molecular kit. Thr model I built is 2-butene because the double bond is located at the 2nd carbon atom. I chose butene because it has 4 carbon atoms and 8 Hydrogen atoms. Each Hydrogen atom forms 1 single bond each with the Carbon atom. The 1st and 4th Carbon atom form 3 single bonds with 3 Hydrogen atoms and 1 single bond with another Carbon atom. The 2nd and 3rd Carbon atoms form 2 single bonds with 2 Hydrogen atoms and 1 double bond with each other. There are no 11 bonded pairs ans no lone pairs in this structure. All the 4 valence electrons of the Carbon atoms form bonds with other atoms. All the 1 valence electrons of the Hydrogen atoms also form bonds with the Carbon atoms. I think this structure is very interesting because it looks very beautiful and I like how all the atoms are connected with one another without any lone pairs. 2-Butene is a colorless gas. One of its uses in daily life is as a cross-linking agent. However, its main use is in the production of gasoline (petrol) and butadiene, although some 2-butene is also used to produce the solvent butanone via hydration to 2-butanol followed by oxidation.
