The correct order of basicity of the following compounds is

$Benzamide$ $\xrightarrow{Br_2 / NaOH} X$ $\xrightarrow[\text{alc. } KOH]{CHCl_3} Y$
The conversion of $X$ to $Y$ is

When aniline reacts with $NaNO_2$ and dil. $HCl$ at $0^{\circ} - 5^{\circ}C,$ the product formed is

What will be the products $A$,$B$,and $C$ in the following reaction sequence?
$\text{Phenol}$ $\xrightarrow[\text{Distillation}]{\text{Zn}} A$ $\xrightarrow[\text{conc. } H_2SO_4]{\text{conc. } HNO_3, 60^{\circ}C} B$ $\xrightarrow[\text{NaOH (aq)}]{\text{Zn}} C$

For the diazonium ions,the order of reactivity towards the diazo-coupling with phenol in the presence of dilute $NaOH$ is:
$(I)$ $Me_2N-C_6H_4-N_2^+$
$(II)$ $O_2N-C_6H_4-N_2^+$
$(III)$ $CH_3O-C_6H_4-N_2^+$
$(IV)$ $CH_3-C_6H_4-N_2^+$

Write the reactions of $(i)$ aromatic and $(ii)$ aliphatic primary amines with nitrous acid.
