Vedclass · Answer

(B) When salicylaldehyde $(2-hydroxybenzaldehyde)$ is heated with zinc dust,the phenolic $-OH$ group is reduced to a hydrogen atom,and the aldehyde group is also reduced to a methyl group,resulting in the formation of toluene $(C_6H_5CH_3)$. However,in the context of standard textbook reactions where zinc dust is used to reduce phenolic groups,the product is often identified as benzaldehyde if the reaction conditions specifically target the $-OH$ group. Given the options provided,the most chemically accurate transformation for salicylaldehyde with zinc dust is the reduction of the phenolic $-OH$ to $H$,yielding benzaldehyde $(C_6H_5CHO)$.

Salicylaldehyde on heating with zinc dust gives . . . . . . as the organic product.
