Chapter 18, Problem 18.22P

(a)

Interpretation Introduction

Interpretation:

The distribution of oxygen-18 in the products obtained from hydrolysis of ethyl benzoate labeled in the ethoxy oxygen in aqueous sodium hydroxide has to be given.

Concept introduction:

Ester Hydrolysis: Ester hydrolysis can be caused by acid and base.

Saponification: Ester hydrolysis taking place in presence of base such as NaOH or KOH is known as saponification. Ester reacts with hydroxide ion forming carboxylic acid which again reacts with base resulting in the formation of a caboxylate anion.

Acid-catalyzed hydrolysis: In presence of strong acid such as H2SO4, ester reacts with water to form the corresponding alcohol and carboxylic acid. It is the reverse of esterification.

(b)
