Answer:
SN1 -
- Unimolecular NSR
- It is two step mechanism
- step (1) is reversible, slow and rate determining.
- intermediate is carbocation so rearrangement, expansion also possible.
- step (2) is faster one because cation has incomplete octate so have strong tendency to accept electron pair from nucleophile.
SN2 -
- Bimolecular nucleophilic reaction
- It is single step mechanism
- attack of nucleophile and leaving of LG is simultaneously occur.
- No cation, no rearrangement.
- Transition state is form.
- It is second order kinetics.
