A. saponification
B. dehydration
C. esterification
D. hydrolysis
Correct Answer:
Option C – esterification
Explanation
Esterification is a chemical reaction that forms at least one ester (= a type of compound produced by reaction between acids and alcohols). Esters are produced when acids are heated with alcohols in a process called esterification. An ester can be made by an esterification reaction of a carboxylic acid and an alcohol.
