Chromic acid and alcohol reaction
Web* The alcohol and chromic acid form chromium (VI) monoester, which may react intra-molecularly or inter-molecularly in presence of a base (H 2 O in this case) to give the corresponding carbonyl compound and chromium(IV) acid. The intra-molecular reaction occurs by way of a β-elimination through a cyclic transition state. * The aldehydes, which ... WebPotassium permanganate (KMnO 4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols. Under controlled conditions, KMnO 4 oxidizes primary alcohols to carboxylic acids very efficiently.
