Question:
Which reagent will best convert alcohol to aldehyde selectively?
Which reagent will best convert alcohol to aldehyde selectively?
Show Hint
When selectively oxidizing alcohols, PCC is a preferred reagent as it stops at the aldehyde stage.
Updated On: June 02, 2025
- KMnO4
- PCC
- K2Cr2O7
- HNO3

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Pyridinium chlorochromate (PCC) is the most selective reagent for the oxidation of primary alcohols to aldehydes. It avoids further oxidation to carboxylic acids, which other reagents like KMnO4 and K2Cr2O7 tend to do. Therefore, PCC is ideal for the selective oxidation of alcohols to aldehydes without over-oxidation.
