Consider the following two reactions. Which is more highly regioselective, and why? Reaction 1 `Cl + HCl Reaction 2 + HCl `Cl O Reaction 1, because the regioselectivity is determined by the difference in E, leading to a 1° versus a 3° carbocation, while in Reaction 2, both products are formed from a 3° carbocation. O They should have exactly the same regioselectivity, because both reactions can give 1-chloro-1- methylcyclohexane. O Reaction 1, because the regioselectivity is determined by the difference in Ea leading to a 1° versus a 3° carbocation, which is greater than the difference in E, leading to a 2° versus a 3° carbocation. O Reaction 1, because the regioselectivity is determined by the difference in Ea leading to a 1° versus a 2° carbocation, which is greater than the difference in E, leading to a 2° versus a 3° carbocation. Reaction 2, because the regioselectivity is determined by the difference in Ea leading to a 2° versus a 3° carbocation, which is greater than the difference in Ea leading to a 1° versus a 3° carbocation.
