$p$-cresol and $1$-methoxy-$4$-ethylbenzene

Vedclass · Answer

(A) Reaction $I$: The cleavage of $p$-methylanisole with $HI$ occurs. Since the bond between the oxygen and the aromatic ring is strong due to resonance,the $C-O$ bond between the methyl group and oxygen breaks,yielding $p$-cresol ($4$-methylphenol) as the major product $X$ and $CH_3I$.Reaction $II$: This is a Wolff-Kishner reduction of $4$-methoxyacetophenone. The carbonyl group $(C=O)$ is reduced to a methylene group $(CH_2)$. Thus,the product $Y$ is $1$-methoxy-$4$-ethylbenzene.Therefore,the products $X$ and $Y$ are $p$-cresol and $1$-methoxy-$4$-ethylbenzene respectively.
