Chapter 21, Problem 21.17P

Interpretation Introduction

(a)

Interpretation:

The product of the given Wittig reaction is to be drawn.

Concept introduction:

The Wittig reaction utilizes carbon nucleophile from the Wittig reagent to yield alkenes. When a carbonyl compound is treated with a Wittig reagent, the $\text{C}=\text{O}$ bond of carbonyl is replaced by $\text{C}=\text{C}$, with by-product triphenylphosphine oxide $\left({\text{Ph}}_{\text{3}}\text{P}=\text{O}\right)$.
