Which of the following is an amide________________?
Correct answer: B. RCONH2
- A. R-NH2
- B. RCONH2
- C. R - NH - R
- D. C6H5NH2
Explanation
An amide contains a carbonyl group directly attached to nitrogen, represented by RCONH2. R-NH2 and R-NH-R are amines, while C6H5NH2 is an aromatic amine called aniline. The likely mistake is aniline because it contains nitrogen, but it lacks the carbonyl group required for 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.
