Chapter 19.5, Problem 8PTS

(a)

Interpretation Introduction

Interpretation: The plausible mechanism for the given transformation has to be drawn.

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.

ORGANIC CHEMISTRY (LL) >CUSTOM PACKAGE<, Chapter 19.5, Problem 8PTS , additional homework tip  1

In acidic condition, an aldehyde or a ketone reacts with two molecules of alcohol or a molecule of diol to form acetal or cyclic acetal respectively.

General scheme:
