16.4 Write the chemical equation for preparing sodium soap from glyceryl oleate and glyceryl palmitate. Structural formulae of these compounds are given below.

(i) (C₁₅H₃₁COO)₃C₃H₅ – Glyceryl palmitate

(ii) (C₁₇H₃₂COO)₃C₃H₅ – Glyceryl oleate

16.4 

Soaps are metallic salts of higher fatty acids such as palmitic acid, stearic acid, oleic acid etc. The process of saponification involves the hydrolysis of an oil or fat with an alkali (sodium hydroxide or potassium hydroxide). Oils and fats are glyceryl esters of fatty acids and may be regarded as mixed glycerides. Sodium soaps are prepared by heating the fats by sodium hydroxide.
