The azo-dye $(Y)$ formed in the following reactions is: $\text{Sulphanilic acid} + NaNO_2 + CH_3COOH \rightarrow X$; $X + \text{1-naphthylamine} \rightarrow Y$. Identify $Y$.

Which among the following statements is true about the reactivity of haloarenes towards nucleophilic substitution reactions?
$1$. Haloarenes are very reactive towards nucleophilic substitution reaction.
$2$. In haloarenes,the $C-X$ bond acquires partial double bond character.
$3$. The $C-X$ bond in haloarenes is longer than the $C-X$ bond in haloalkanes.
$4$. In haloarenes,the phenyl cation formed as a result of self-ionisation is stable.

Which of the following groups acts as both $-I$ effect and $o, p$-directing group?

$STATEMENT-1$: Bromobenzene upon reaction with $Br_2 / Fe$ gives $1,4$-dibromobenzene as the major product.
$STATEMENT-2$: In bromobenzene,the inductive effect of the bromo group is more dominant than the mesomeric effect in directing the incoming electrophile.
