Question

The most suitable reagent for the conversion of \( \text{R-CH}_2\text{-OH} \) to \( \text{R-CHO} \) is:

Hint:

PCC is ideal for oxidizing primary alcohols to aldehydes without forming carboxylic acids.

Answer 1

Pyridinium chlorochromate (PCC) selectively oxidizes primary alcohols (\( \text{R-CH}_2\text{-OH} \)) to aldehydes (\( \text{R-CHO} \)), preventing further oxidation to carboxylic acids.
Conclusion: PCC is the optimal reagent.
