The most suitable reagent for the conversion of
`RCH_(2)OHrarrRCHO` is

A

`KMnO_4`

B

`K_2Cr_2O_7`

C

`CrO_3`

D

PCC (Pyridine chloro chromate)

Text Solution

Verified by Experts

The correct Answer is:
D
The alcohol can be converted to aldehyde group by treating with oxidising agent Pyridinium chloro chromate `(C_6H_5 overset(o+)NHCrO_3Cl^(-))` it is abbreviated as PCC and is called Collin.s reagent. This reagent is used in non aqueous solvent like `CH_2Cl_2` It is a very good reagent because it checks the further oxidation of aldehyde to carboxylic acid while rest oxidising agent oxidise aldehyde into carboxylic acid.
