Compare the reactivity of iodine with cyclohexene to its reactivity with α-pinene and explain the differences. Cyclobutanes have about 25-27 kcal/mole ring strain. Considering the mechanism for the reaction of α-pinene with I2, would you predict the energy difference between a secondary and a tertiary carbocation to be more or less than 27 kcal/mole?
