Question
Consider the reaction of 2-bromobutane (where the stereocenter is in the "R" configuration) with OH-. How many of the following statements are true?
1. An inversion of stereochemistry would indicate the reaction proceeded through a first order process
2. The reaction could proceed through either an SN1 or SN2 mechanism. Information about the stereochemistry of the reaction or rate law would be needed to determine which mechanism was used
3. If the reaction proceeds through an SN1 mechanism two alcohol products will be formed: 1 "R" and 1 "S"
4. If the reaction proceeds through an SN2 mechanism one alcohol product will be formed, the "R" isomer
5. If the reaction goes through an SN1 mechanism it means the pathway for secondary carbocation formation was lower in energy than the pathway for the attack of a nucleophile on the secondary alkyl halide
