Identify $A$ and predict the type of reaction.
$3\text{-bromoanisole} \xrightarrow{NaNH_2} A$

$STATEMENT-1$: 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.

Which one of the following is least reactive in a nucleophilic substitution reaction?

Which of the following statements are correct?
$A$. The $C-Cl$ bond in chlorobenzene is shorter than in chloromethane.
$B$. It is more difficult to replace chlorine from chlorobenzene than from benzyl chloride.
$C$. The $C-Cl$ bond in chlorobenzene has some double bond character.
$D$. Chlorobenzene on chlorination gives $m$-dichlorobenzene.

Replacement of $Cl$ of chlorobenzene to give phenol requires drastic conditions,but $Cl$ of $2,4$-dinitrochlorobenzene is readily replaced. This is because,

Which of the following reasons support that aryl halides are less reactive than alkyl halides towards nucleophilic substitution reactions?
$a)$ The formation of more stable arenium ion
$b)$ Partial double bond character of $C-X$ bond
$c)$ Longer $C-X$ bond
$d)$ $sp^2$ carbon bonded to $X$ is more electronegative
