Step-by-step Solution
Detailed explanation
Pyridinium chlorochromate (PCC) can be prepared by the dissolution of chromium trioxide in aqueous \(\mathrm{HCl}\). Addition of pyridine gives pridinium chlorochromate as orange cryotol. PCC offers the advantage of the selective oxidation of alcohols to aldehydes, whereas many…
