Homework Answers
Oxidation of alcohol to aldehyde is carried out with a very mild oxidation agent CO, taking a strong oxidation agent will further oxidise it to carboxylic acid.
correct options are:- Pyridinium cholorochromate, Dess- Martin periodinane and Swern Oxidation method ( where DMSO and (COCl)2 in CH2Cl2 solvent is used)
NaBH4 or sodium borohydride is a reducing agent, while Chromic acid is a strong oxidising agent
