The most suitable reagent for the conversion of R C H 2 O H → R C H O is
Options
- AK M n O 4
- BK 2 C r 2 O 7
- CC r O 3
- DP C C
Correct answer
D. P C C
Step-by-step solution
The alcohol can be converted to aldehyde group by treating with oxidising agent Pyridinium chloro chromate ( C 5 H 5 N ⊕ H C r O 3 C l - ) it is abbreviated as P C C and is called Collin's reagent. This reagent is used in non aqueous solvent like C H 2 C l 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.
