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

Question

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

Step-by-Step Solution

Answer

Cyclopentanol can be formed in the following way:

Step-by-step solution Step 1: Hydroboration

It means substitution of one hydrogen from the reactant, so that alcohol group 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 cyclopentanol

The desired product cyclopentanol can be prepared by hydroboration or oxidation of  cyclopantene. 

The reaction is as follows:
