Question

The most suitable reagent for the conversion of RCH2OH arrow RCHO is :- (A) K2Cr2O7 (B) CrO3 (C) KMnO4 (D) PCC

The oxidation of primary alcohols leads to formation of aldehydes.

R - C H_{2} - O H Oxidising Agent R - C H O

.
Pyridinium chlorochromate

(PCC)

is a milder version of chromic acid.

PCC

oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. Similar to or the same as:

C r O_{3}

and pyridine (the Collins reagent) will also oxidize primary alcohols to aldehydes.
