Vedclass · Answer

(B) The starting material is a $\beta$-keto acid. Upon heating $(\Delta)$,it undergoes decarboxylation to form a ketone. The reaction is: $	ext{Cyclohexyl-CO-CH}_2	ext{COOH} \xrightarrow{\Delta} 	ext{Cyclohexyl-CO-CH}_3 + 	ext{CO}_2$. Thus,product $(A)$ is acetylcyclohexane (or cyclohexyl methyl ketone). Next,the Clemmensen reduction $(Zn(Hg)/HCl)$ reduces the carbonyl group $(C=O)$ to a methylene group $(CH_2)$. Therefore,$	ext{Cyclohexyl-CO-CH}_3 \xrightarrow{Zn(Hg)/HCl} 	ext{Cyclohexyl-CH}_2	ext{CH}_3$. The final product $(B)$ is ethylcyclohexane.

In the above reaction,product $(B)$ is:
