Jones reagent

Jones reagent (chromic acid in aqueous acetone solution)

Chromic acid,  H2CrO4 , is a strong acid in presence of acetone it act as good oxidising agent also know as Jones oxidising agents and is a reagent for oxidizing alcohols to ketones and carboxylic acids. 

In place of comic acid we can use Na₂CrO₄  (sodium chromate),  Na₂Cr₂O₇  (sodium dichromate),  KCrO₄  (potassium chromate),  K₂Cr₂O₇  (potassium dichromate), and  CrO₃  (chromium trioxide) are alike in one crucial manner: when they are combined with aqueous acid, each of them forms  H₂CrO₄ , and ultimately it is  H₂CrO₄  that is involved in the important chemistry.

Application of Jones Reagent

This is a sufficiently mild oxidising agent, so that it oxidises alcohols without oxidising or rearranging double bonds. MnO₂ can oxidise 1° allylic or 1° benzylic alcohols selectively into aldehydes.

Example of Jones reagent (chromic acid in aqueous acetone solution)
