Chapter 12, Problem 29P

(a)

Interpretation Introduction

Interpretation:

The product of the given reaction has to be identified.

Concept Introduction:

Acetals:

Acetals are used to protect the ketone and aldehyde (carbonyl group).

In this reaction acetone is protected as acetal by using ethylene glycol. Acetals are less stable compound.
