Which of the following is not the property of ethanenitrile `(CH_3CN)` ?

Options

A. Undergoes acidic hydrolysis to give carboxylic acid
B. Undergoes alkaline hydrolysis to give salt of carboxylic acid
C. It tautomerises to give methyl isocyanide
D. It gives carbylamine reaction with chloroform

Answer

D

Explanation

Carbylamine reaction is given by aliphatic and aromatic primary amine
`CH_(3)CN` does not give carbylamine reaction with chloroform because it is not an amine.
`CH_(3)CN` undergoes acidic hydrolysis to give carboxylic acid
`CH_(3)CN overset(H_(2)O//H^(+))rarr CH_(3)CONH_(2) overset(H_(2)O//H^(+))rarr underset("acetic acid")(CH_(3)COOH)+ NH_(3)`
`CH_(3)CN` undergoes alkaline hydrolysis to give salt of carboxylic acid
`CH_(3)CN underset(H_(2)O)overset(NaOH)rarr CH_(3)CONH_(2) underset(H_(2)O)overset(NaOH)rarr underset("sodium acetate")(CH_(3)COONa+ NH_(3))`
`CH_(3)CN` tautomerises to give methyl isocyanide.
`CH_(3)-C -= N hArr C -= N- CH_(3)`
