Interpretation Introduction

(a)

Interpretation:

The structure of the alkene formed by the reaction of ethyl iodide with ${\text{Ph}}_{\text{3}}\text{P}$, butyllithium and acetone is to be drawn.

Concept introduction:

The reaction of an aldehyde or a ketone with ethylidene triphenylphosphorane that is phosphorous Ylides results in the formation of alkene as the final product. This reaction is commonly known as Wittig reaction.
