Correct answer: A. 5
- A. 5
- B. 2
- C. 4
- D. 3
Explanation
There are five functional groups present in the given formula. of the dipeptide: Carboxylic acid [COOH) group: one at the N-terminus of aspartic acidAmine (NH2) group: one at the C-terminus of phenylalanine Amide (O-C-NH) group: one linking the two amino acids Ester (O=C-O-) group: one in the side chain of aspartic acid Phenyl (benzene ring) group: one in the side chain of phenylalanine

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.
