WebBy using jones reagent , we get RCHO group ie , an aldehyde. Jones reagent is a relatively mild oxidising agent. Only a strong oxidising ahent such as chromic acid (H2CrO4) could oxidise an alcohol to carboxylic acid. The oxidising order is as follows - alkanes -> alcohols -> aldehydes -> carboxylic group 1 comment ( 11 votes) Upvote Downvote Flag WebJan 23, 2024 · PCC oxidizes alcohols one rung up the oxidation ladder, from primary alcohols to aldehydes and from secondary alcohols to ketones. In contrast to chromic acid, PCC will not oxidize aldehydes to carboxylic acids.

WebOxidation with the PCC reagent converts 1º-alcohols to aldehydes; whereas Jones reagent continues the oxidation to the carboxylic acid product, as shown in the second reaction. … WebPCC is one of the reagents of choice for oxidation of pri-mary alcohols to aldehydes and secondary alcohols to ke-tones. 13,14. Unlike CrO. 3, PCC has a long shelf life and better solubility in organic solvents. One of the major problems in oxidation reactions using chromium is its car-cinogenicity. Recently, 15. we have shown that PCC can be
WebThe aldehyde which is produced can be oxidized further to the carboxylic acids by the use of acidified potassium dichromate (VI) solution that is used as an oxidizing agent. The net effect occurs as the oxygen atom of the oxidizing agent eliminates the hydrogen atom from the hydroxyl (-OH) group of alcohol and also one carbon atom attached to it.
