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. WebAlkyl halides undergo elimination via two common mechanisms, known as E2 and E1, which show some similarities to S N 2 and S N 1, respectively. In E2, elimination shows a second order rate law, and occurs in a single concerted step (proton abstraction at C α occurring at the same time as C β-X bond cleavage). In E1, elimination goes via a first order rate law, …
