Chapter 20, Problem 20.10P

Interpretation Introduction

(a)

Interpretation:

The structure of the product formed when $\text{3-methylhexanoic}\text{acid}$ is heated with a large excess of ethanol with sulfuric acid catalyst is to be stated.

Concept introduction:

An ester is formed by the reaction of carboxylic with alcohol in the presence of an acid catalyst. This reaction is known as esterification.

Esters end with a suffix, $-oate$. They are always present in the middle of the carbon chain. The carbon chain which is not bonded to the carbon of the ester group is named first, and then the carbon chain which includes the ester group $-\text{COO}-$ is named.
