Vedclass · Answer

(A) Chromic acid in aqueous acetone at $5 - 10^{\circ}C$ is known as the $Jones$ reagent.It is a selective oxidizing agent that oxidizes secondary alcohols to ketones and primary alcohols to carboxylic acids.$A$ key feature of the $Jones$ reagent is that it does not oxidize or affect carbon-carbon double or triple bonds.In option $(A)$,a secondary alcohol containing a triple bond is correctly oxidized to a ketone while the triple bond remains intact.Options $(B)$ and $(D)$ show primary alcohols being oxidized to aldehydes,which is incorrect as the $Jones$ reagent typically oxidizes primary alcohols to carboxylic acids.Option $(C)$ requires much stronger oxidizing conditions.

Which of the following oxidation reactions can be carried out with chromic acid in aqueous acetone at $5 - 10^{\circ}C$?
