Answer 1

2) Answer is C). In polar aprotic solvent, SN2 reaction takes place and inverted product is formed.

3) Answer is A). Elimination takes place with loss of HI.

4) Answer is C). Because benzene is monosubstituted thus give either Ortho, meta or para product.

5) Answer is C). Due to polarizability, negative charge get stabilized.

6) Answer is C). SN1 reaction is independent on concentration of nucleophile and depends only on concentration of Alkyl hailde.
