What will be the product $A$ in the following reaction?
$C_6H_5CCl_3 \xrightarrow{1 \text{ eq. of } Br_2/Fe} A$

$C_6H_5NH_2$ $\xrightarrow[\substack{NaNO_2 \\ HCl, 0-5^{\circ}C}]{} X$ $\xrightarrow[CuCl]{HCl} Y$ $\xrightarrow[\text{dry ether}]{CH_3Cl, Na} Z$
What is $Z$ in the sequence of reactions?

Describe the reaction of chlorobenzene with a hydroxyl group (nucleophilic substitution).

$STATEMENT-1$: 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.

$CH \equiv CH$ $\xrightarrow{\text{Red Hot Fe tube}} A$ $\xrightarrow[\text{Dark}]{Cl_2 / FeCl_3} B$ $\xrightarrow[\text{Anhy. } AlCl_3]{CH_3 - Cl} C$ (Major)
Product '$C$' is
