The best reagent to convert pent-3-en-2-ol into pent-3-en-2-one is
Options:
A .  
Acidic permanganate
B .  
Acidic dichromate
C .  
Chromic anhydride in glacial acetic acid
D .  
Pyridinium chloro-chromate
Answer: Option C : C Strong oxidising agents like acidified KMnO4 or K2Cr2O7 oxidised alcohols to carboxylic acids. For oxidation of primary alcohols to ketones, Pyridinium chloro-chromate(PCC) is used and for oxidation of secondary alcohols to ketones, Chromic anhydride in glacial acetic acid is used.
