Q10-25E-b - Organic Chemistry (Mcmurry)

Question

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

Step-by-Step Solution

Answer

Methylcyclopentane can be formed in the following way:

Step-by-step solution Step 1: Chlorination

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

Step 2: Alkyl halide

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

Step 3: Preparation of methylcyclopentane

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

The reaction is as follows:
