Homework Answers
As you haven't mentioned which question is to be answered,as per our guideline i am attending the first one.
This is a simple SN2 type reaction,where the neucleophile attacks at the electrophilic center and the leaving group goes out.
Now see the mechanism and try to get it
Hope you are satisfied with my
answer, have a good day.
