Question:
The IUPAC name of the compound
\(\mathrm{CH_3-CH_2-N(CH_3)-C(=O)-H}\)
The IUPAC name of the compound
\(\mathrm{CH_3-CH_2-N(CH_3)-C(=O)-H}\)
\(\mathrm{CH_3-CH_2-N(CH_3)-C(=O)-H}\)
Show Hint
When naming amides, consider the groups attached to the nitrogen and the carbonyl group to determine the correct IUPAC name.
Updated On: Apr 22, 2026
- N-methylpropanamide
- N-ethylmethanamide
- N-methylacetamide
- N-ethylacetamide
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Analyze the structure.
The compound is:
\[
\text{CH}_3\text{CH}_2\text{-N(CH}_3\text{)-CHO}
\]
- Nitrogen has two substituents: ethyl and methyl
- Functional group is amide (methanamide base)
Step 2: Correct IUPAC name. The correct name should be: \[ \text{N-ethyl-N-methyl methanamide} \]
Step 3: Match with options. - (1) Incorrect - (2) Correct name but mismatch in given options context - (3) Incorrect - (4) Correct as per given choices Conclusion: Since the correct IUPAC name is not properly matching the listed options, the answer is (4) None of the above.
Step 2: Correct IUPAC name. The correct name should be: \[ \text{N-ethyl-N-methyl methanamide} \]
Step 3: Match with options. - (1) Incorrect - (2) Correct name but mismatch in given options context - (3) Incorrect - (4) Correct as per given choices Conclusion: Since the correct IUPAC name is not properly matching the listed options, the answer is (4) None of the above.
