${C_6}{H_5}N{H_2}\mathop {\xrightarrow{{NaN{O_2}/HCl}}}\limits_{0 - 5\,^o C} X\mathop {\xrightarrow{{HN{O_2}}}}\limits_{C{H_2}O} Y + {N_2} + HCl$
$X$ and $Y$ are respectively
because
$STATEMENT$-$2$: The small size of $\mathrm{B}^{3+}$ favours formation of covalent bond.
Statement $I :$ Aniline is less basic than acetamide.
Statement $II :$ In aniline, the lone pair of electrons on nitrogen atom is delocalised over benzene ring due to resonance and hence less available to a proton.
