WebApr 7, 2024 · Chromic Acid (Jones) Test A solution of CrO 3 in H 2SO 4 is a test for polar functional groups that can be oxidized, which includes aldehydes, primary alcohols, and secondary alcohols (Figure 6.57). Tertiary alcohols … 4 CrO 3 → 2 Cr 2 O 3 + 3 O 2. It is used in organic synthesis as an oxidant, often as a solution in acetic acid, [8] or acetone in the case of the Jones oxidation. In these oxidations, the Cr (VI) converts primary alcohols to the corresponding carboxylic acids and secondary alcohols to ketones.
