Vedclass · Answer

(C) The reaction of a Grignard reagent $(PhMgBr)$ with formaldehyde $(HCHO)$ followed by acid hydrolysis $(H_3O^+)$ yields a primary alcohol. Specifically,the nucleophilic phenyl group $(Ph^-)$ attacks the electrophilic carbonyl carbon of formaldehyde $(HCHO)$,forming an intermediate alkoxide $(Ph-CH_2-O^-)$. Subsequent protonation by acid results in the formation of benzyl alcohol $(Ph-CH_2OH)$. Therefore,the compound $X$ is formaldehyde.

Phenylmagnesium bromide,upon reaction with a compound $X$ followed by treatment with acid,gives benzyl alcohol. The compound $X$ is
