2. What is the catalyst for the hydration of ethene into ethanol?

  • Phosphoric acid
  • Potassium (VIII) manganate

3. What are some of the issues with bioethanol and biodisel?

  • It uses large areas of land and has substantial costs in processing and manufacture
  • Engines will have to be drastically remodeled to run it
  • It is non renewable
  • It is not as close to carbon neutral as some fossil fuels such as coal

4. Why is 2-Bromopropane the major product of the reaction of propene and HBr?

  • Because the intermediary carbocation is more stable (the charge is spread over more atoms)
  • There is less steric hinderance for the reaction compared to 1-Bromopropane
  • The H will attack where there are fewer H's already
  • It is not, the products are equally likely as propene is symmetrical

  • 3-methylhexanol
  • 2,2,-dimethylbutan-4-ol
  • 3,3-dimethylbutan-1-ol
  • 2-ethylbutan-4-ol
