How many of the following specific reagents convert 1-propanol exclusively to propanal without formi — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

$KMnO_4/H^+$, $K_2Cr_2O_7/H^+$, and $CrO_3$ in aqueous medium are strong oxidants that form carboxylic acids. The selective mild reagents that stop at the aldehyde stage are PCC, PDC, Collin's reagent, and vapour phase dehydrogenation over $Cu/573K$. Thus, there are 4 correct reagents.
