Which one of the following compounds does not react with acetyl chloride?
- A \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{NH}_2\)
- B \(\mathrm{CH}_3 \mathrm{CH}_2 \mathrm{CH}_2 \mathrm{NHCH}_3\)
- C \(\left(\mathrm{CH}_3 \mathrm{CH}_2\right)_3 \mathrm{~N}\)
- D \(\left(\mathrm{CH}_3\right)_3 \mathrm{CNH}_2\)
Answer & Solution
Correct Answer
(C) \(\left(\mathrm{CH}_3 \mathrm{CH}_2\right)_3 \mathrm{~N}\)
Step-by-step Solution
Detailed explanation
Aliphatic and aromatic primary and secondary amines undergo acylation reaction as these amines contain replaceable hydrogen atoms (positively polarised H ) on the nitrogen atom. Triethylamine, i.e., \(\left(\mathrm{CH}_3 \mathrm{CH}_2\right)_3 \mathrm{~N}\) is a tertiary amine, without any replaceable H -atom. Thus, it will not react with acetyl chloride.
