Allylic and benzylic alkyl halides undergoes SN1 because these are form resonance stabilized carbocation intermediate.
The rate of SN1 reaction is only depends on the concentration of alkyl halide but not on the concentration of nucleophile. So double the concentration of KI doesn't change the rate of reaction.

Question 1: Find a table that compares the relative reaction rates (Su2) for alkyi fluorides, chlorides, bromides and iodides (Section 9.2 in the textbook). Which halide is the best leaving group? How much faster is it than the slowest halide leaving group? Question 2: The nature of the solvent plays a big role in determining the type of substitution or elimination mechanism that takes place (SH1, SN2, E1 or E2). Draw structures for 2...
