Chapter 8, Problem 8.68EP

(a)

Interpretation Introduction

Interpretation: The total number of water molecules that participates in the reaction if a simple triacylglycerol undergoes complete acidic hydrolysis has to be predicted.

Concept introduction: The hydrolysis of triacylglycerol is carried out in the presence of an acid or a base. The hydrolysis of triacylglycerol takes place in the presence of an acid forms glycerol and fatty acid as the desired products. The hydrolysis of triacylglycerol takes place in the presence of a base forms glycerol and fatty acid salts as the desired products.

The process of converting a fat or oil into the fatty acid salts and glycerol in the presence of water and a base like $\text{NaOH}$ is known as saponification.
