Which one of the following compounds does not react with acetyl chloride?
Options
- ACH ₃ CH ₂ NH ₂
- BCH ₃ CH ₂ CH ₂ NHCH ₃
- C( CH ₃ CH ₂ )₃ ~N
- D( CH ₃ )₃ CNH ₂
Correct answer
C. ( CH ₃ CH ₂ )₃ ~N
Step-by-step solution
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., ( CH ₃ CH ₂ )₃ ~N is a tertiary amine, without any replaceable H -atom. Thus, it will not react with acetyl chloride.
