Which one among the following is not a good leaving group?
- A
HSO4-
- B
Cl-
- C
OH-
- D
Br-
Option C is correct.
OH- is not a good leaving group. A good leaving group is an ion that can easily leave a molecule without causing much disruption to the molecule. A good leaving group is usually a negatively charged ion with a relatively small size. is very strong nucleophile and due to its high charge to size ratio, it is strongly attached to carbon and hence a poor leaving group.
HSO4- is larger ion with a negative charge, which makes it stable and less likely to leave the molecule.
Cl- is larger ion with a negative charge, which makes it stable and less likely to leave the molecule.
