In which of the following amides is a -NH₂ group present? A) acetamide B) N-methylpropanamide C) 2-methylbutanamide D) more than one correct response E) no correct response

Question

Quizplus · Accepted Answer

The -NH₂ group, also known as the succinimidyloxycarbonyl (SOC) group, is present in N-succinimidyl esters which are commonly used as coupling reagents for peptide synthesis. N-methylpropanamide and 2-methylbutanamide both contain an amide functional group that can be used for peptide synthesis with N-succinimidyl esters. Therefore, the correct answer is D - both N-methylpropanamide and 2-methylbutanamide contain a -NH₂ group.
