Step-by-step solution

Pyridinium chlorochromate (PCC) can be prepared by the dissolution of chromium trioxide in aqueous HCl . Addition of pyridine gives pridinium chlorochromate as orange cryotol. PCC offers the advantage of the selective oxidation of alcohols to aldehydes, whereas many other reagents are less selective.
