1.homologus series is a series in which all the compounds have same general formula,similar chemical propeties but have some functional group differing
2.An alkane consists of hydrogen amd carbon atoms arranged in a tree structure
3.alkene is a hydro carbon consisting of carbon carbon double bond

1.  Homologous series is a collection of compounds with same general formula but different carbon chain.
2. Alkene have double bonds while alkane have single bond.
3. It is the study of structure,properties and preparation of carbon containing chain

->organic chemistry refers to the study of materials or compounds containing atoms of carbon except a few which includes: carbon dioxide, carbon monoxide and carbonates.
-> It includes the study of different groups of compounds having similarities, which are known as homologus series. Three main series are known as Alkane, Alkene, Alcohol.

1.Organic chemistry is the scientific study of structures, properties and reactions of organic compounds.
2.Compounds which contain carbon(C) are organic compounds but have some exceptions like metal carbonates,CO2,CO are not included in organic compounds
3.Organic compounds containing similar chemical properties are sorted in series known as Homologous Series. examples include Alkane, Alkene, Alcohol, Carboxylic Acids, Esters, Cycloalkane etc.
4.Alkane is a saturated hydrocarbon series which means it doesn't have any functional group thus it is not reactive however goes under combustion and substitution reaction.
5. Rest all homologous series have a functional group which is the reactive part.
examples include (c=c) in alkene, O-H in alcohol, COOH in carboxylic acid.
6. Furthermore all the homologous series have a general formula which helps in deducing the formulas of the organic compounds in a particular homologous series.
7. Organic compounds have isomers which means same molecular formula but different structural formula

1.Organic chemistry is regarding hydrocarbons Which Are the compounds of hydrogen and carbon only.
2. There are different types of homologous series. Firstly all the compounds in homologous series have similar chemical properties and are differentiated by CH2 group. Different types of series are Alkanes are saturated hydrocarbons while alkenes are unsaturated hydrocarbons. Other examples include alcohols and carboxylic acid.
3. All the homologous series except alkane also have isomers which have the same same chemical formulae but different structural formulae

..>From alkenes, we can make many isomers and Cyclo alkane .
..> the branch of chemistry that deals with carbon compounds (other than simple salts such as carbonates, oxides, and carbides).

-Homologous series such as alkane alkene alcohols and a homologous series have similar properties
-Alkene are unsaturated compounds.
-Ester are formed through the reaction of alcohols and carboxylic acids.
