Vedclass · Answer

(D) The conversion of primary alcohols $(R-CH_2OH)$ to aldehydes $(RCHO)$ requires a mild oxidizing agent that stops the oxidation at the aldehyde stage without further oxidizing it to a carboxylic acid. $PCC$ (Pyridinium chlorochromate) is a selective oxidizing agent that performs this specific transformation efficiently. Strong oxidizing agents like $KMnO_4$,$K_2Cr_2O_7$,and $CrO_3$ (in acidic medium) typically oxidize primary alcohols directly to carboxylic acids.

Which of the following reagents is most suitable for the conversion of $R-CH_2OH$ to $RCHO$?
