Chromic acid and alcohol reaction
WebChromic acid is not stable over time and is prepared by mixing a dichromate salt, usually sodium. or potassium dichromate, with sulfuric acid. The reaction of chromic acid with a secondary. alcohol involves several steps, in which the oxidation state of chromium is changed from +6 to +3, but the slowest step involves the decomposition of a ... WebJones oxidation is a common protocol for the synthesis of carboxylic acids from primary alcohols in the presence of a wide variety of functional groups. The basis of Jones …
