Interpretation Introduction

(a)

Interpretation:

The structure of the cyclic anhydride formed by the given dicarboxylic acid when heated is to be drawn.

Concept introduction:

The term anhydride means “without water”. The anhydride can be formed of carboxylic acids either by using dehydrating agents or heating the carboxylic acid. The formation of anhydrides of dicarboxylic acids resulting in the formation of five or six-membered ring structures is readily formed on heating.

Interpretation Introduction

(b)

Interpretation:

The structure of the cyclic anhydride formed by the meso-α,β-dimethylsuccinicacid dicarboxylic acid when heated is to be drawn.

Concept introduction:

The term anhydride means “without water”. The anhydride can be formed of carboxylic acids either by using dehydrating agents or heating the carboxylic acid.
