Chapter 16.6, Problem 16.5P

(a)

Interpretation Introduction

Interpretation:

Show how the given alkene can be synthesized by a Wittig reaction.

Concept introduction:

The functional group in the aldehydes and Ketones are carbonyl group.

Wittig reaction is a reaction in which a nucleophilic elimination occurs after nucleophilic addition reaction. In this reaction an aldehyde or ketone reacts with a triphenyl phosphonium ylide (Wittig reagent) to give an alkene and triphenylphosphine oxide.

The reaction can be represented as shown below,
