Vedclass · Answer

(A) $1$. The formula $C_9H_{12}O_2$ and the reaction with $Na$ indicate the presence of hydroxyl groups. $2$. The reaction with $KMnO_4$ (reflux) oxidizes alkyl side chains on a benzene ring to carboxylic acids. $3$. The reaction with $CrO_3/H^+$ (Jones reagent) under cool conditions selectively oxidizes primary and secondary alcohols to carboxylic acids and ketones,respectively. $4$. Structure $(A)$ is $1-(4-(	ext{hydroxymethyl})	ext{phenyl})	ext{ethanol}$. $5$. It is optically active due to the chiral center at the carbon bearing the secondary hydroxyl group. $6$. Oxidation of $(A)$ with $KMnO_4$ yields terephthalic acid $(C_8H_6O_4)$. $7$. Oxidation of $(A)$ with $CrO_3/H^+$ yields $4-(	ext{acetyl})	ext{benzoic acid}$ $(C_9H_8O_3)$. $8$. Structure $(B)$ is not optically active as it lacks a chiral center.
