WebStep 1: Sulfuric acid ionizes to give a proton H 2 SO 4 → H + + HSO 4– Step 2: Proton formed in step 1 reacts with OH group and forms OH 2+ and loss of water gives positive charge on the carbon atom and forms a tertiary carbocation. Step 3: Removal of hydrogen adjacent to the tertiary carbocation gives alkene (Double bond formation). WebObjectives: Upon completion of the course the student shall be able to.
