Homework Answers
Alkyl Iodide is more reactive towards SN2 reaction than alkyl bromide. Since, iodine is bigger in size than Bromine so the bonds get longer so weaker the bond, the more easily it is broken (making iodide the good leaving group), the lower the activation energy for the reaction and the faster the rate at which it will occur.Also, iodine is less electronegative than bromine so the carbon-halide bonds is weaker in iodine than bromine , making alkyl iodidemore reactive.

3. An alkyl halide is reacted with sodium iodide and sodium chloride in separate test tubes. The rate was the same in both experiments. Is this an Syl or an SN2 reaction? How would you know? 4. Why is sodium iodide used as a solution in acetone in these experiments instead of a solution in water? 5. Will the reaction below be Spl or Sn2? Show the mechanism.

c. The reaction of triphenylphosphine with an alkyl halide is a
bimolecular nucleophilic substitution (SN2) reaction in which
triphenylphosphine is the nucleophile and the alkyl halide is
theelectrophile. Is triphenylphosphine acting like a Lewis acid,
Lewis base, Bronsted-Lowry acid, orBronsted-Lowry base? How would
you characterize the behavior of the alkyl halide?
d. In the lab, you will make your ylide by reacting
benzyltriphenylphosphonium bromide with sodium hydroxide. How would
you characterize this reaction?
