Ethylbenzene

Vedclass · Answer

(A) The given reaction involves two steps: $1$. Clemmensen reduction: The ketone group $(C=O)$ is reduced to a methylene group $(-CH_2-)$ using $Zn-Hg/HCl$. The reactant is $3-ethylhexan-3-one$ (or a similar ketone structure). The reduction converts the carbonyl group into a methylene group,resulting in an alkane chain. $2$. Dehydrocyclization (Aromatization): The resulting alkane is treated with $Cr_2O_3$ at $773 \ K$ and $10-20 \ atm$. This is a standard industrial process for the aromatization of alkanes to form aromatic hydrocarbons. Given the structure,the alkane formed is $3-ethylhexane$. Upon aromatization,it cyclizes to form ethylbenzene.
