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.
