  • (a)Homolytic (b) Sunlight and warm conditions (c) Nucleophilic substitution
  • (a) Homolytic (b) UV light (c) Free radical substitution
  • (a) Heterolytic (b)UV light (c) Free radical substitution

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

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

4. The C=C double bond is....

  • ... not quite twice as strong as the C-C bond, due to the presence of the pi bond
  • ... more than twice as strong as the C-C bond due to the electron-dense sigma bond
  • ...made of 2 pi bonds, overlapping end-on
  • ....made of p-orbitals that overlap sideways to form a sigma bond, split in electron density above and below the nuclei plane

5. 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
