Which of the following compound is an amide?
Correct answer: B. NH2COCH3
- A. NH4CNO
- B. NH2COCH3
- C. NH2CONH2
- D. NH2COONH
Explanation
OPTION A: NH4CNO is not an amide because it contains a nitrogen atom bound to hydrogen, not to a carbonyl group (C=O).OPTION B: Amides are functional groups in which a carbonyl carbon atom is linked by a single bond to a nitrogen atom and either a hydrogen or a carbon atom. OPTION C: NH2CONH2 is not an amide because it is a peptide bond, not a molecule containing an amide functional group (R-C(=O)-NR'2).OPTION D: NH2COONH is not an amide because it lacks the carbonyl group (C=O) that is essential for an organic compound to be classified as an amide.

About Functional Groups
Functional groups are specific atoms or atom groups that determine the characteristic reactions and properties of organic compounds. Coverage includes alkenes, alkynes, halo, hydroxyl, ether, carbonyl, carboxyl, ester, amino and nitro groups, together with their structures, nomenclature and related homologous series.
