Introduction:
In this reaction, toluene undergoes oxidation with CrO3 and (CH3CO)2O to form benzaldehyde. The benzaldehyde is then hydrolyzed with dilute hydrochloric acid (HCl) to give the final product.
Reaction:
The reaction can be represented as follows:
Toluene + CrO3 + (CH3CO)2O → Benzaldehyde + Chromium(VI) oxide + Acetic acid
Benzaldehyde + HCl + H2O → Benzoic acid + Chloride ion
Explanation:
1. Oxidation of Toluene:
Toluene (C6H5CH3) reacts with CrO3 (chromium(VI) oxide) and (CH3CO)2O (acetic anhydride) to undergo oxidation. The CrO3 acts as an oxidizing agent and converts the methyl group (CH3) of toluene into an aldehyde group (-CHO), forming benzaldehyde (C6H5CHO).
2. Hydrolysis of Benzaldehyde:
The benzaldehyde formed in the previous step is then hydrolyzed with dilute hydrochloric acid (HCl) and water (H2O). The benzaldehyde molecule reacts with HCl to form benzoic acid (C6H5COOH) and chloride ion (Cl-).
Overall Reaction:
The overall reaction can be represented as follows:
Toluene + CrO3 + (CH3CO)2O + HCl + H2O → Benzaldehyde + Benzoic acid + Acetic acid + Chromium(VI) oxide + Chloride ion
Conclusion:
Thus, when toluene is treated with CrO3 and (CH3CO)2O followed by hydrolysis with dilute HCl, it undergoes oxidation and forms benzaldehyde. The benzaldehyde is then further hydrolyzed to give benzoic acid as the final product.
