Oxidation of toluene with chromyl chloride gives benzaldehyde which react with acetic anhydride to give benzylidene acetate and thus, further oxidation of benzaldehyde to benzoic acid is checked by acetic anhydride. The benzylidene acetate on treatment with HCl regenerates benzaldehyde.

Q. Statement 1 : Oxidation of toluene with chromyl chloride to get benzaldehyde is carried out in presence of acetic anhydride.
