Why do solvents with low dielectric constants favor SN2 reactions?
1 Answer
Jan 8, 2018
Solvents with low dielectric constants did not interfere the nucleophilic's attack, while the high dielectric constants solvent did it.
Explanation:
The mechanism of SN2 reaction occurs concerted. So, the nucleophilicity is important. The polar solvent (high dielectric constants) solve (as solvent) nucleophile with electropositive charge. This causes the nucleophilicity decreases.
