Answer to Question 1



Answer to Question 2



Answer to Question 3

The structure represents a tertiary alkyl halide, which does not undergo SN2 reactions. A tertiary alkyl
halide normally undergoes SN1 reactions, but this alkyl halide cannot form a planar carbocation due to
geometrical constraints.



Answer to Question 4

a

Answer to Question 5

b

Answer to Question 6

e
