Vedclass · Answer

(A) Alkyl isocyanides $(R-NC)$ undergo hydrolysis in the presence of acid to form alkyl formamides $(R-NH-CHO)$.In the mechanism,the terminal carbon atom of the isocyanide group possesses a lone pair and a partial negative charge,allowing it to act as a nucleophile and get protonated by $H^+$.After protonation,the carbon atom becomes electron-deficient (electrophilic) and is subsequently attacked by water $(H_2O)$.The reaction sequence is: $R-N \equiv C$ $\xrightarrow{H^+} R-N^+ \equiv CH$ $\xrightarrow{H_2O} R-N=C(H)(OH) \rightleftharpoons R-NH-CHO$.

Assertion : Alkyl isocyanides in acidified water give alkyl formamides.
Reason : In isocyanides,carbon first acts as a nucleophile and then as an electrophile.
