During the formation of an acid amide from ethanoic acid and ammonia, 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
The overall transformation involves replacing the hydroxyl (-OH) group of the carboxylic acid with an amino (-NH2) group. This proceeds via an ammonium salt intermediate which is then dehydrated.

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.
