Concept:Saponification of fats and oils produces glycerol, which is a trihydric alkanol.
Explanation:Soap is manufactured by the alkaline hydrolysis of fats and oils.
Fats and oils are naturally occurring esters called triglycerides.
They are formed from glycerol and long-chain fatty acids.
When these esters are boiled with
NaOH, they undergo saponification.
The reaction yields soap and glycerol as products.
Glycerol, also known as propane-1,2,3-triol, contains three hydroxyl (
−OH) groups.
An alkanol with three hydroxyl groups is classified as a trihydric alkanol.
Thus, the alkanol obtained during soap production is a trihydric alkanol.
Answer:C. Trihydric Alkanol
