Interpret reaction pathway diagrams showing

exothermic and endothermic reactions

Name and draw the structural and displayed

formulae of unbranched:

(a) alkanes

(b) alkenes, including

but-1-ene and but-2-ene

(c) alcohols, including

propan‑1‑ol, propan‑2‑ol, butan‑1‑ol and

butan‑2‑ol

(d) carboxylic acids

containing up to four carbon atoms per

molecule

to fix my mistakes I will revisit these los once again solving questions and rereading from textbook, I will solve more past papers and identify more los where I am going wrong.

1 Describe the transition elements as metals that:

(a) have high densities

(b) have high melting points

(c) form coloured compounds

(d) often act as catalysts as elements and in

To fix these mistakes, I will thoroughly read these topics again, and solve topic wise questions. Moreover, I will make notes regarding these topics which I can easily revisit during the exam. I will also reconsider my revision techniques so that I can efficiently remember every information before the exam.

1. exo and endothermic reaction

2. ATP tests in theory paper

3. acid bases and salts reaction

4. properties or characteristics of metals, non metals and transition metals

5. Moles questions such as finding number of molecules and finding number and empirical formula

1. stoichiometry

2. structures of polymers, labeling and drawing repeat units

3. naming complex polymers

4. flame tests, anion, cation test

5. neutralizing soil

I should, revise the topics I am facing trouble in, and solve specific topic based questions. use the syllabus guide to revise, make concise notes and mind maps so it will be easier to relate topics with each other, increasing my retention of more difficult topics

Compare the general physical properties of

metals and non-metals, including:

(d) melting points and boiling points

Describe the properties of alkanes as being

generally unreactive, except in terms of

combustion and substitution by chlorine

Describe the manufacture of alkenes and

hydrogen by the cracking of larger alkane

molecules using a high temperature and a

catalyst.

-reaction pathway diagram labelling activation energy and enthalpy change.

-identify two covalent structures shown above.

-identifying the monomer from a given polyester structure

-drawing structures of compounds after cracking

-Calculating the number of molecules from a given number

• why a specific indicator is not suitable for a reaction

• naming reducing and oxidizing agents from given equation.

• substances which are present in the blast furnace , and why limestone is added to blast furnace.

• sacrificial protection.

  *Topics which need more practice -

• Polymerisation

• Cracking alkanes

• Esterification

• Oxidation and Reduction

• Moles and finding yield percentage

1.diagrams of covalent molecules

2.metals and alloys (should had worked on concepts )

3.displayed formula

4.base of all concepts (chapters)

5.displayed formula drawing

6.symbol equations

7.polymerisation

pathway diagrams incorrect interpretation

complete word equations

ionic and covalent bonding

acids and bases reacting with salts

need to work on polymers and organic chemistry a lot

mole concept and solving numericals

blast furnace

work on word equations

work on topics unsure about and cannot understand

read the textbook more before the exams

make more summary notes ands do more past papers than currently solving.will clarify doubts regularly,will also refer and read through syllabus sheet
