Question

Which of the following reagents cannot be used to oxidise primary alcohols to aldehydes? (A) CrO3 in anhydrous medium (B) KMnO4 in acidic medium (C) Pyridinium chlorochromate (D) Heat in the presence of Cu at 573 K

KMnO 4 in acidic medium cannot be used t oxidise primary alcohols to aldehydes because convert primary alcohols into carboxylic acid th direct oxidation of primary alcohols to carboxyli acids can be cartied out using KMnO 4. CH3CH2OH xrightarrow[H+]K/MnO4 CH3COOH

Q. Which of the following reagents cannot be used to oxidise primary alcohols to aldehydes?

$C r O_{3}$ in anhydrous medium

$K M n O_{4}$ in acidic medium

Pyridinium chlorochromate

Heat in the presence of $C u$ at $573 K$

$K M n O_{4}$ in acidic medium cannot be used $t$ oxidise primary alcohols to aldehydes because convert primary alcohols into carboxylic acid th direct oxidation of primary alcohols to carboxyli acids can be cartied out using $K M n O_{4}$ .
