K2cr2o7 is oxidising or reducing agent

WebbBy 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. WebbAnswer (1 of 2): I expect that CrO_3 is a stronger oxidizing agent. Since CrO_3 is a covalent component, there are no formal charges in the molecule. On the other hand, (Cr2O7)^= contains extra electrons. Despite the Cr being hexavalent in both molecules, …
