Chromic Acid Reactions

  • Primary Alcohols to Carboxylic Acids: Chromic acid oxidizes primary alcohols first into aldehydes and then straight through to carboxylic acids.

  • Secondary Alcohols to Ketones: Secondary alcohols are oxidized cleanly into ketones.

  • Aldehydes to Carboxylic Acids: Aldehydes are rapidly oxidized to carboxylic acids (via a gem-diol intermediate in aqueous acid).

  • Tertiary Alcohols: Do not react because they lack an alpha-hydrogen atom. [1, 2, 3, 4]
