      Benzil to Benzilic Acid. To determine the amount of 6M potassium hydroxide to add, the mass of the dry benzil was multiplied by 2.5. For the amount of 95% ethanol to use, the mass of dry benzil was multiplied by 3. Benzil was then combined with these two liquids in a round bottom flask. A stir bar was added and the flask was then attached to a ...

      The conversion of Benzil to Benzilic acid was first studied by Friedrich Wohler and Justin von Lieberg and is one of the first known rearrangement reactions in organic chemistry. It is a great reaction to introduce students to complex reaction mechanisms. Since Benzil is required to form Benzilic acid, it must first be synthesized from Benzoin.
