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 ... WebChromic acid cleanly oxidizes secondary alcohols to ketones using acetones as solvent and the product isolation is simple. The terpene borneol (with an endo-secondary hydroxyl group, -OH) is oxidized to camphor as below: Oxidation of borneol is an exothermic reaction, in order to avoid creation of side product; the experiment should be carried ...
