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: Jan 13, 2026
- KMnO4
- PCC
- K2Cr2O7
- HNO3
Show Solution
The Correct Option is B
Solution and Explanation
Pyridinium chlorochromate (PCC) offers superior selectivity in oxidizing primary alcohols to aldehydes, preventing the over-oxidation to carboxylic acids commonly observed with reagents such as KMnO4 and K2Cr2O7. Consequently, PCC is the preferred choice for precise alcohol to aldehyde transformations.
