Answer» Acidic permanganate Acidic dichromate Chromic ANHYDRIDE in GLACIAL acetic acid Pyridinium chloro-chromate Solution :Pyridinium chlorochromate `(PC C, CrO_(3), C_(2)H_(5)N.HCl)` has an advantage over other oxidising agents that the oxidation of `1^(@)` alcohol stops at aldehyde STAGE (oxidation of aldehyde to carboxylic acid is prevented) and `2^(@)` alcohol containing doube bond is oxidised to ketone retaining the double bond (double bond is not AFFECTED).
