Benzaldehyde and $H_2 + Pd$

Vedclass · Answer

(B) The reaction of toluene with chromyl chloride $(CrO_2Cl_2)$ followed by hydrolysis is the Etard reaction,which produces benzaldehyde $(P = C_6H_5CHO)$.To convert benzaldehyde $(C_6H_5CHO)$ to benzoic acid $(C_6H_5COOH)$,an oxidizing agent is required.Among the given options,the reaction sequence $P$ (benzaldehyde) $\xrightarrow{R}$ benzoic acid requires an oxidation step.However,looking at the options provided,there is a mismatch in the standard reagents. The oxidation of benzaldehyde to benzoic acid is typically done using $KMnO_4$ or $K_2Cr_2O_7$. Given the options,if we assume the question asks for the product $P$ and a reagent $R$ that could potentially oxidize it,none of the reagents listed ($HI$,$H_2+Pd$,$Zn-Hg/HCl$) are standard oxidants. Re-evaluating the provided options: Option $B$ identifies $P$ correctly as benzaldehyde. If the question implies a typo in the reagent $R$ or a specific context,$P$ is definitely benzaldehyde.

Identify $P$ and $R$ in the given reaction sequence:
$Toluene$ $\xrightarrow[(2) H_3O^+]{(1) CrO_2Cl_2} P$ $\xrightarrow{R} Benzoic \ acid$
