Answer 2

Pyridium Chloro Chromate (PCC) is the best reagent to convert pent-3-en-2-ol into pent-3-en-2-one.

This is a way of oxidation of alcohol. The given alcohol being a tertiary one does not undergo direct oxidation or dehydrogenation. Pyridium chloro chromate is a less reactive version of chromic acid.

Conversion of primary or lower alcohols to aldehydes and upper alcohols to their respective ketones is the speciality of this mildly acidic reagent.
