Interpretation: Step-wise synthesis of
Concept introduction:
Radical halogenation is a substitution reaction in which hydrogen atoms of
One problem with alkane halogenations is that multiple substitutions occur unless an excess of alkane is used.
At normal temperature and pressure, chlorine and methane do not react with each other. The reaction is initiated by light or heat. If they are exposed to light,
The reaction that is initiated by light is more efficient because a very small amount of photons allows a large number of products to form.

- (a) Tsomane and Nyiko were given a task of synthesising methylenecyclohexane 2. After a brief discussion with each other, Tsomane proposed Method A to synthesise 2 from cyclohexanone 1 while Nyiko proposed Method B that started from hydroxymethylcyclohexane 3. Each student believed that their proposed method is better than the other.
