During the formation of an acid amide from ethanoic acid, what actually happens:
Correct answer: B. Displacement of the -OH from the acid by -NH2
- A. Displacement of the -H from the acid by-Cl
- B. Displacement of the -OH from the acid by -NH2
- C. Attachment of -NH2 with the carbonyl oxygen
- D. Displacement of the -H from the acid by -NH2
Explanation
Carboxylic acids react with ammonia to form ammonium salts which on heating produce acid amides. Functional group of carboxylic acid is a combination of carbonyl group and hydroxal group.During this reaction,it's hydroxal group is replaced by -NH2 and forms acetamide that contains carbonyl and amino group as functional group.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
