OCHEM transition states and reaction rates

  1. Apr 17, 2010 #1
    1. The problem statement, all variables and given/known data
    Explain why 2-bromopropane reacts with NaI in acetone over 10^4 times faster than bromocyclopropane. (Hint: examine the transition state for each of the reactions)

    2. Relevant equations

    3. The attempt at a solution
    I understand this is a sn2 type reaction and therefore is completed in one step. Is bromocyclopropane's transition more sterically hindered than 2-bromopropane?

    Draw the structure for both. Remember to accurately represent the cyclopropate ring. Look at all the angles.
