Answer-2
In SN1 reactions the intermediate formed is carbocation, the geometry of carbocation is trigonal planner.
The nucleophile can attack form above or below the plane of carbocation.
Therefore there is 50% retention and 50% inversion in SN1 reactions.
Answer 21-
Halogens are very good leaving group. Poor bases are good leaving group.
So answer is -Cl- .
