Homework Answers
a. The above reaction diagram is represented by both SN1 and E1 because in both mechanism the product are obtained through two step process in which first step is carbocation formation and the second step in SN1 is attacking of nucleophile while in E1 is removing of H ion to form alkene.
b. Doubling the concentration of a nucleophile or base does not affect the rate of the reaction because both SN1 and E1 are first order reaction and their rate depends on the concentration of a reactant not nucleophile or a base.
c. The best electrohpile will be 3o for both SN1 and E1.
