Step-by-step solution
Toluene reacts with chromyl chloride ( CrO ₂ Cl ₂ ) in CS ₂ to form a brown chromium complex intermediate, C ₆ H ₅ CH ( OCrOHCl ₂)₂ . This is the Etard reaction. Thus, (A) matches with (I). Toluene reacts with chromic oxide ( CrO ₃ ) in acetic anhydride to form benzylidene diacetate, C ₆ H ₅ CH ( OCOCH ₃)₂ . Thus, (B) matches with (II). Side chain chlorination of toluene with Cl ₂ in the presence of sunlight gives benzal chloride, C ₆ H ₅ CHCl ₂ . Thus, (C) matches with (III). Strong oxidation of toluene with alkal
