Question

How would you prepare the following compounds, starting with cyclopentene and any other reagents needed? (b) Methylcyclopentane.

Short answer

Methylcyclopentane can be formed in the following way:

Step-by-step solution

Step-by-step solutionStep 1: Chlorination

It means substitution of one hydrogen from the reactant, so that halogen atom can be added there.

Alkyl halide

Alkyl halides are also known as haloalkanes or halogenoalkanes. They contains one or more halogen substituents i.e. –Br, -Cl,-I,-F.

Preparation of methylcyclopentane

The desired product methylcyclopentane can be prepared by brominating cyclopantene and then reducing bromocyclopantane to methylcyclopentane.

The reaction is as follows:
