NEET levelSingle correct optionDifficulty 1 of 3o1118

Acetaldehyde reacts with methylamine, $CH X_{3} NH X_{2}$ , under mild acid catalysis with loss of water. The product is

AN-methylacetamide
BN-ethylmethanamine
Cethanenitrile
DN-methylethanimine, $CH X_{3} - CH = N - CH X_{3}$

Answer: D

A primary amine adds to an aldehyde to give a carbinolamine, which loses water to form a C=N bond (imine, Schiff base):

CH X_{3} CHO + CH X_{3} NH X_{2} CH X_{3} CH = NCH X_{3} + H X_{2} O
