WebJones reagent, which is a mixture of chromic acid (H2CrO4) and sulfuric acid (H2SO4), is commonly used to oxidize alcohols to their corresponding carbonyl compounds. When a primary alcohol is treated with Jones reagent, it is oxidized to an aldehyde and then to a carboxylic acid. WebAldehydes are oxidized by chromic acid, ketones are not. When an aldehyde is oxidized by orange-brown chromic acid the chromic acid is reduced to Cr+3, which is green. Consequently, chromic acid can distinguish between aldehydes and ketones. It is also true that other functional groups, primary and secondary alcohols for example,
