This is my notes on ozone depletion, covered in the topic on halogenoalkanes. This includes the equations for conversion of ozone into oxygen, and how a chlorine radical acts as a catalyst.

An overview of the free radical substitution of alkanes to produce halogenoalkanes. Including intitiation, propogation and termination steps.

A general overview of alkanes, their general formula, drawing alkanes, isomerism displayed in alkanes, and cycloalkanes.

These are my notes on combustion of alkanes, covered in the alkanes module of AS AQA organic chemistry.

These are my notes on cracking hydrocarbons, to produce alkenes, aromatic compounds and smaller alkanes.

These are my notes on fractional distillation of crude oil. This only applies to crude oil and not the topic on alcohols, or making aspirin in A2.

These are my AQA AS chemistry notes on naming organic compounds. This only applies to branched hydrocarbons, halogenoalkanes, alkenes and alcohols. This does not apply to aromatic compounds, amines or any derivatives covered in A2.

These are my notes for isomerism. This only includes structural and stereoisomerism, and NOT optical isomerism, as that is covered in A2 Chemistry.

This is my notes for AQA AS Chemistry, covering all of the organic chemistry modules, including introduction to organic chemistry, alkanes, halogenoalkanes, alkenes, alcohols and organic analysis. These include all mechanisms, all test tube reactions, isomerism, fractional distillation, free radical substitution and MORE!

This is the official 2023 AQA A LEVEL BIOLOGY paper 2, IT CONTAINS ALL QUESTIONS.
