PCC is :
- K2Cr2O7 + Pyridine
- CrO3 + CHCl3
- CrO3 + H2SO4
- A complex of chromium trioxide with pyridine + HCL
The Correct Option is D
Approach Solution - 1
- Pyridinium chlorochromate (PCC) is a mild oxidizing agent used primarily to oxidize primary alcohols to aldehydes and secondary alcohols to ketones without affecting other functional groups.
- PCC is prepared by reacting chromium trioxide (CrO₃) with pyridine and hydrochloric acid (HCl), forming a complex that is the actual oxidizing agent.
Thus, PCC is a complex of chromium trioxide with pyridine and HCl, making option (D) the correct answer.
Approach Solution -2
Pyridinium chlorochromate (PCC) is a reagent formed by reacting chromium trioxide (CrO₃) with pyridine, and often involves the addition of HCl to complete the preparation. PCC is a mild oxidizing agent that selectively oxidizes primary alcohols to aldehydes and secondary alcohols to ketones.
