JEE Main 2024 Chemistry question
In the given reactions, identify the reagent A and reagent B. Toluene → ["A" + (CH₃CO)₂O, 273–283 K] → [Intermediate] → H₃O⁺, Δ → benzaldehyde; and toluene → ["B" + CS₂] → [Intermediate] → H₃O⁺ → benzaldehyde.
Answer: (B)
Solution
Toluene with CrO₃ and acetic anhydride (Étard-type oxidation via the benzylidene diacetate, then H₃O⁺/Δ) gives benzaldehyde,
