Saponification is the hydrolysis of fat or oil with an__________________?
Correct answer: B. Alkali
- A. Acid
- B. Alkali
- C. Enzyme and alkali
- D. Enzyme and acid

About Carboxylic Acid Derivatives
Carboxylic acid derivatives include acid halides, acid anhydrides, esters and amides, formed by replacing the hydroxyl group of a carboxylic acid. Their nomenclature, structures, preparation, hydrolysis and relative reactivity are linked through nucleophilic acyl substitution, which differs from the nucleophilic addition reactions of aldehydes and ketones.
