  2. ACID CATALYZED HYDRATION OF ALKENE Chapter 8

  3. OBJECTIVE Chapter 8

  4. DISCUSS THE REACTION INVOLVED IN THE PREPRATION OF ALCOHOL FROM ALKENE Chapter 8

  5. METHODOLOGY • LECTURE METHOD • DISCUSSION METHOD Chapter 8

  6. Hydration of Alkenes • Reverse of dehydration of alcohol • Use very dilute solutions of H2SO4 or H3PO4 to drive equilibrium toward hydration. => Chapter 8

  7. => Mechanism for Hydration Chapter 8

  8. => Orientation for Hydration • Markovnikov product is formed. Chapter 8

  9. REVISION Chapter 8

  10. Acid Catalyzed Hydration of Alkenes Chapter 8

  11. Mechanism Step 1 Note the electronic structure of the oxonium ion. Step 2 Step 3 Chapter 8

  12. EVALUATIONORRECAPITUATION • EVALUATION CAN BE DONE BY PUTTING , ASKING QUESTIONS RELATED TO TOPIC Chapter 8

  13. EVALUATION • Ques1.:- Give the structure and IUPAC name of the major product expected from the acid catalyzed hydration of propene? • Ques2.:- Describe the different steps involved in preparation of alcohol from alkene(mechanism) How propene converted into propan-2-ol. • Ques3.:- Give the mechanism of hydration of ethene to yield ethanol Chapter 8

  14. THANK YOU Chapter 8
