$4-$Ethylphenol

Vedclass · Answer

(A) The $-OCH_3$ group is an electron-donating group and is ortho/para directing. In aromatic electrophilic substitution,the para position is favored due to steric hindrance at the ortho position.Step-$1$: Friedel-Crafts Acylation of anisole with $CH_3COCl$ and anhydrous $AlCl_3$ yields $4$-methoxyacetophenone as the major product.Step-$2$: Clemmensen reduction of $4$-methoxyacetophenone using $Zn-Hg$ and concentrated $HCl$ reduces the acetyl group to an ethyl group,forming $4$-ethylanisole.Step-$3$: Cleavage of the ether linkage in $4$-ethylanisole with $HI$ yields $4$-ethylphenol and methyl iodide $(CH_3I)$.Thus,the major product is $4$-ethylphenol.

The major product of the following reaction sequence is:
