Final answer:
PCC oxidizes secondary alcohols to ketones without further oxidation.
Step-by-step explanation:
When a secondary alcohol reacts with PCC (pyridinium chlorochromate), it undergoes oxidation to form a ketone. PCC is a mild oxidizing agent that selectively oxidizes secondary alcohols to ketones without further oxidation. For example, when 2-propanol (a secondary alcohol) is reacted with PCC, it forms propanone (or acetone) which is a ketone. This reaction can be represented as follows:
R₂CHOH + PCC → R₂C=O
