Chapter 21, Problem 21.47P
Interpretation Introduction

(a)

Interpretation: The carbonyl compound and alcohol formed by the hydrolysis of the given compound are to be stated.

Concept introduction: Acetals are the groups in which carbon atom is bonded to two OR groups through single bonds. They are used as protecting groups as they are stable enough in neutral to strong basic condition. However, they are unstable in acidic media, and dissociates into corresponding alcohol and carbonyl compound.
