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) is used to selectively oxidize primary alcohols (\( \text{R-CH}_2\text{-OH} \)) to aldehydes (\( \text{R-CHO} \)) without further oxidation to carboxylic acids.
Conclusion: The most suitable reagent is PCC.
