Vedclass · Answer

(A) Step $1$: Primary alcohols $(R-CH_2OH)$ are oxidized to aldehydes $(R-CHO)$ and further to carboxylic acids $(R-COOH)$ by strong oxidizing agents.Step $2$: $K_2Cr_2O_7 / 	ext{dil. } H_2SO_4$ and acidic $KMnO_4$ are strong oxidizing agents that oxidize primary alcohols directly to carboxylic acids.Step $3$: $CrO_3$ in anhydrous conditions can stop at the aldehyde stage, but $PCC$ (Pyridinium chlorochromate) is specifically designed to oxidize primary alcohols to aldehydes without further oxidation to carboxylic acids.Step $4$: Therefore, $PCC$ is the correct reagent to limit the oxidation to the aldehyde stage.

Which of the following reagents limits the oxidation of $R-CH_2OH$ to $R-CHO$ only?
