Question

Toluene on treatment with CrO3 and (CH3CO)2O followed by hydrolysis with dil HCl gives (A) benzaldehyde (B) benzoic acid (C) phenol (D) phenylacetaldehyde

Tardigrade Admin · Accepted Answer

The reagent CrO3 |(CH3CO)2O|H+ acts as oxidising agent and oxidises the side chain. Toluene on treatment with CrO3 and (CH3CO)2O followed by hydrolysis with dil HCl gives benzaldehyde <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/de8945e7dd4735fc2ced0861d184e593-.png" />

Q. Toluene on treatment with $C r O_{3}$ and $(C H_{3} CO)_{2} O$ followed by hydrolysis with dil $H Cl$ gives

benzaldehyde

benzoic acid

phenol

phenylacetaldehyde

The reagent $C r O_{3} ∣ (C H_{3} CO)_{2} O ∣ H^{+}$ acts as oxidising agent and oxidises the side chain. Toluene on treatment with $C r O_{3}$ and $(C H_{3} CO)_{2} O$ followed by hydrolysis with dil $H Cl$ gives benzaldehyde
