Question:
PCC is :
PCC is :
Updated On: Mar 29, 2025
- K2Cr2O7 + Pyridine
- CrO3 + CHCl3
- CrO3 + H2SO4
- A complex of chromium trioxide with pyridine + HCL
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
- 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.
