Question

Question:  Propose structures for compounds that fit the following descriptions:

(a) An alkyl halide that gives a mixture of three alkenes on E₂ reaction

Step-by-Step Solution

Answer

Answer:

Step 1: E 2 reaction

It is a nucleophilic elimination reaction in which an old bond is broken and a new bond is formed both the process occur simultaneously and no intermediate is formed.

Here, the carbon-hydrogen or halogen bond breaks to form a new double bond. Hence, it’s a single-step reaction.

Step 2: Formation of alkene

When an alkyl halide undergoes an elimination reaction with nucleophilic species forms alkene by the removal of alkyl halide as shown:
