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

Carbykamine reaction is given by aliphatic and aromatic primary amine.
`CH_3CN` does not give carbylamine reaction with chloroform because it is not an amine .
`CH_3CN` undergoes acidic hydrolysis to give carboxylic acid.
`CH_3CN underset"Partial hydrolysis"overset(H_2O // H^+) to CH_3CONH_2 underset"Complete hydrolysis " overset(H_2O // H^+) to underset"Acetic acid"(CH_3COOH)+CH_3`
`CH_3CN` undergoes alkaline hydrolysis to give salt of carboxylic acid .
`CH_3CN underset(H_2O)overset(NaOH)to CH_3CONH_2 underset(H_2O)overset(NaOH)to underset("Sodium acetate" ) (CH_3COoverset-Ooverset+Na)+ NH_3`
`CH_3CN` tautomerises to give methyl isocyanide.
`CH_3-C -= N hArr C overset(larr)= N -CH_3`
