QuestionReaction mechanism / solvent effects (Hughes-Ingold rules)
Consider the following statements regarding Reaction I and Reaction II :
Reaction I : HO⁻ + CH₃OSO₂Ph —SN2→ CH₃OH + PhSO₂O⁻
Reaction II : N(CH₂CH₃)₃ + CH₃CH₂I —SN2→ (CH₃CH₂)₄N⁺I⁻
- With increase in solvent polarity, the rate of Reaction I is slightly reduced.
- With increase in solvent polarity, the rate of Reaction I is slightly increased.
- With increase in solvent polarity, the rate of Reaction II is greatly increased.
- With increase in solvent polarity, the rate of Reaction II is greatly decreased.
Which of the statements given above are correct ?
- (a) 1 and 3
- (b) 1 and 4
- (c) 2 and 3
- (d) 2 and 4
