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

The correct statements about the products $B$ and $C$ in the given reactions are
$CH_3CH_2OH$ $\xrightarrow[\text{Anhy } ZnCl_2]{HCl} A$ $\xrightarrow[\text{AgCN}]{\text{ethanolic}} \underset{\text{Minor}}{B} + \underset{\text{Major}}{C}$
$I$. $B$ and $C$ are functional isomers
$II$. With $H_2 / \text{Catalyst}$,$B$ gives $1^{\circ}$ amine and $C$ gives $2^{\circ}$ amine
$III$. $B$ on acid hydrolysis gives formic acid and $C$ gives $C_3H_6O_2$
$IV$. $C$ forms isocyanate with $HgO$

In the reaction sequence,
$X$ and $Y$ are,respectively

Among the following,which one does not act as an intermediate in the Hofmann rearrangement?

Identify the final product $Z$ in the following reaction sequence:

Which of the following substituents,when attached at the para-position of aniline,decreases its basicity?
