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

A

`KMnO_(4)`

B

`K_(2)Cr_(2)O_(7)`

C

`CrO_(3)`

D

PC C (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_(6)H_(5)overset(o+)(N)HCrO_(3)CI^(-))` it is abbreviated as PCC and is called Collin's reagent. This reagent is used in non aqueous solvent like `CH_(2)CI_(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.
