Q8P-b - Organic Chemistry (Mcmurry)

Question

How would you prepare the following alkyl halides from the corresponding alcohols?

Step-by-Step Solution

Answer

The given compound is 2-bromo,4-methylpentane. It can be prepared as the following way:

Step 1: Alkyl halides

Alkyl halides are also known as haloalkanes or halogenoalkanes. They contains one or more halogen (-Cl, -Br, -I, -F) atoms. They are derived from alkanes by replacing one or more H-atom from alkanes.

Step 2: Preparation of given compound

Given compound (b) is a secondary haloalkane. It can be prepared from a secondary alcohol in presence of  /ether or /ether .

2-bromo,4-methylpentane is prepared from 4-methyl,pent-2-ol, with the help of /ether or /ether.

The reaction is as follows:
