Electrolytic reduction of nitrobenzene in weakly acidic medium gives

Given below are two statements:
Statement $I$: Heating benzamide with bromine in an ethanolic solution of sodium hydroxide will give benzylamine.
Statement $II$: Nitration of aniline with $HNO_3/H_2SO_4$ at $288 \ K$ produces $m$-nitroaniline in higher amount than $o$-nitroaniline (pH adjusted).

The reduction of benzenediazonium chloride to phenylhydrazine can be accomplished by:

Which of the following amines will not react with nitrous acid to give nitrogen gas?

Consider the reaction sequence from $P$ to $Q$ shown below. The overall yield of the major product $Q$ from $P$ is $75 \%$. What is the amount in grams of $Q$ obtained from $9.3 \ mL$ of $P$? (Use density of $P = 1.00 \ g \ mL^{-1}$,Molar mass of $C = 12.0, H = 1.0, O = 16.0$ and $N = 14.0 \ g \ mol^{-1}$)

Identify $X$ and $Y$ in the following reactions:
$Nitrobenzene \xrightarrow{Zn/NH_4Cl} X$
$Nitrobenzene \xrightarrow{Zn + KOH/C_2H_5OH} Y$
