Chapter 24, Problem 24.17E

Interpretation Introduction

(a)

Interpretation:

For the acid the α- and β-positions are to be labeled.

Concept introduction:

Fatty acids contain a long side chain of carbon atoms and a carboxylic acid group. For the nomenclature the carbon atom of carboxyl group is labeled as $0$ and the carbon atom adjacent to the carboxylic group is labeled as α-carbon. Similarly, the carbon atom which is adjacent to the α-carbon is known as β-carbon.
