Given a compound with br as leaving group and oh anion as nucleaophile... the other compound with br as leaving group and H2O as nucleophile, which one will react faster?
Accepted Answer
The reaction with OH- as the nucleophile will be faster. Here's why:
Nucleophilicity: OH- is a stronger nucleophile than H2O. This is because the negative charge on OH- makes it more electron-rich and thus more likely to donate electrons to form a new bond.
Leaving Group Ability: Br is a good leaving group in both cases, so this factor doesn't significantly influence the relative reaction rates.
