Question

The most suitable reagent for the selective conversion of a primary alcohol ($RCH_2OH$) to an aldehyde ($RCHO$) without over-oxidation is:

Answer: D

💡 Solution & Explanation

Strong oxidants like $KMnO_4$, $K_2Cr_2O_7$, and aqueous $CrO_3$ will oxidize primary alcohols all the way to carboxylic acids. PCC in an anhydrous solvent stops the oxidation at the aldehyde stage.
