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

Question

How would you prepare the following compounds, starting with cyclopentene and any other reagents needed? (c) 3-Bromocyclopentene.

Step-by-Step Solution

Answer

3-Bromocyclopentene 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 3-bromo-cyclopentene

The desired product 3-bromocyclopentene can be prepared by brominating cyclopantene. 

The reaction is as follows:
