Question

The best reagent to convert pent-3-en-2-ol into pent-3-en-2-one is (A) pyridinium chloro chromate (B) chromic anhydride in glacial acetic acid (C) acidic dichromate (D) acidic permanganate

Tardigrade Admin · Accepted Answer

Sol. Pyridinium chlorochromate oxidises an alcoholic group selectively in the presence of carbon-carbon double bond.

C H_{3} - ∣ O H C H - C H = C H - C H_{3} PCC

C H_{3} - ∣ ∣ O C H - C H = C H - C H_{3}
