Question

Question: What alkane is needed to make each alkyl halide by radical halogenation?

Short answer

Answer

Step-by-step solution

Radical halogenation

The halogenation reaction involving the replacement of a highly reactive hydrogen atom of alkanes or alkyl substituted aromatics by any of the halide ions initiated by either heat or UV light is known as the radical halogenation reaction.

Identifying alkanes

The given alkyl halides are produced by the free-radical halogenation of the following compounds:

a) Replacing the bromide ion by hydrogen atom would give the corresponding alkane.

2-methyl butane

b) The halide ion is replaced by a hydrogen atom to form the corresponding hydrocarbon

Propyl cyclohexane

c) The chloride ion is replaced by the hydrogen atom to form the corresponding alkane.

2,2-Dimethyl propane
