$A$ primary aliphatic amine on reaction with nitrous acid in cold $(273 \, K)$ and thereafter raising the temperature of the reaction mixture to room temperature $(298 \, K)$ gives a/an .....

Identify $X$ and $Y$ in the following reaction: ${C_6H_5NH_2}$ $\xrightarrow[0^{\circ} - 5^{\circ}C]{NaNO_2 + 2HCl} X$ $\xrightarrow[H_2O]{HNO_2} Y + N_2 + HCl$

Consider the following:
Statement-$I$: In the nitration of aniline,a significant amount of $m$-nitroaniline is formed.
Statement-$II$: In the presence of a strongly acidic medium,aniline is protonated to form the anilinium ion,which is meta-directing.

Which of the following compounds is an example of a secondary amine?

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 $HgO$

Predict the product of the reaction of aniline with bromine in a non-polar solvent such as $CS_2$.
