Ethyl methylamine cannot be resolved under normal conditions because

A) The nitrogen atom rapidly inverts its configuration leading to a racemic mixture

B) it isomerizes rapidly with the achiral isomer trimethylamine

C) the favoured configuration is not chiral

D) the C-N bond is not stable under conditions used for resolution

Correct Answer: A

Solution :

[a] The N-atom of ethylmethylamine undergoes fast inversion, so it cannot be resolved under normal conditions.
