Q.28 - Organic Chemistry

Question

What alkyl halide forms each of the following alkenes as the only product in an elimination reaction?

a.

b.

c.

d.

Step-by-Step Solution

Answer

The major alkyl halide as the reactants are shown below:

Position of β hydrogen

The $\mathbf{\text{β}}$  hydrogen position will be such that it exclusively forms the product provided.

Position of the leaving group

The leaving group position decides the product formation. Both the leaving group and  $\text{β}$ hydrogen are in an antiperiplanar position.

 

Based on the mentioned steps, the following alkyl halides are drawn.
