Interpretation: The structural formulas for the product of the complete hydrolysis of tristearin are to be drawn.
Concept introduction: The hydrolysis (saponification) of a triglyceride produces soap. Triglyceride is treated with a strong base, such as sodium hydroxide, to form glycerol and fatty acid salts. Soap is the salt of fatty acids.
Answer to Problem 60A
The structural formulas for the sodium stearate and glycerol are shown below:
Explanation of Solution
Tristearin is a triglyceride made up of three esterified stearic acid residues. Therefore, the complete hydrolysis of tristearin produces three sodium stearate (soap) and one glycerol molecule.
The complete hydrolysis of tristearin is as follows:
The structural formulas for the sodium stearate and glycerol are shown below:
