Vedclass · Answer

(A) The reaction of $2$-substituted cyclohexanone with $KMnO_4$ involves oxidative cleavage of the ring.$KMnO_4$ acts as a strong oxidizing agent that cleaves the $C-C$ bond adjacent to the carbonyl group,resulting in the formation of a keto-acid,$R-CO-(CH_2)_4-COOH$ (which is $A$).Subsequently,the Wolff-Kishner reduction,using $NH_2NH_2$ and $KOH$ followed by $H_3O^+$,reduces the carbonyl group $(C=O)$ to a methylene group $(-CH_2-)$.Therefore,the final product $B$ is $R-CH_2-(CH_2)_4-COOH$,which is $R-(CH_2)_5-COOH$.

$A$ and $B$ in the following reaction are:
