Vedclass · Answer

(D) $1$. Formation of $X$: The reaction of $p$-bromotoluene with $Mg$ in ether forms a Grignard reagent, $p-CH_3-C_6H_4-MgBr$. This reacts with acetaldehyde $(CH_3CHO)$ followed by hydrolysis to give $1-(p-tolyl)ethanol$. The haloform reaction $(Br_2/NaOH)$ on this secondary alcohol oxidizes it to $p$-methylacetophenone, which then undergoes haloform reaction again to produce $p$-toluic acid $(X)$.$2$. Formation of $Y$: $p$-toluic acid $(X)$ reacts with $SOCl_2$ to form $p$-toluoyl chloride, which on reaction with $NH_3$ gives $p$-toluamide. Finally, the Hoffman bromamide reaction $(Br_2/NaOH)$ converts the amide into $p$-toluidine $(Y)$.

The compounds $X$ and $Y$ are respectively:
