Vedclass · Answer

(D) The conversion of $p$-nitrotoluene $(X)$ to $3,5$-dibromotoluene $(Y)$ involves the following steps: $1$. Reduction of the nitro group to an amino group: $p$-nitrotoluene is reduced using $Fe/H^{+}$ to form $p$-toluidine. $2$. Bromination: $p$-toluidine is treated with $Br_2 (aq)$ to form $2,6$-dibromo-$4$-methylaniline due to the strong activating effect of the $-NH_2$ group. $3$. Diazotization: The amino group is converted to a diazonium salt using $HNO_2$ at $0-5 \ ^{\circ}C$. $4$. Deamination: The diazonium group is removed using $H_3PO_2$ and water to yield $3,5$-dibromotoluene $(Y)$.

In the above conversion of compound $(X)$ to product $(Y)$,the sequence of reagents to be used will be:
