There is a 2-iodopentane. Two separate reactions there is acetate ion and -SCH3. Will these go SN2 or E2?
The acetate ion is not a strong base, but will steric hindrance cause it to do mostly elimination?
The -SCH3 is not weak but it's not a strong base, correct? Actually I don't know anything about this molecule. Can someone tell me if it is strong or weak relative to other molecules.

Im pretty sure that -SCH3 will do Sn2 because it is a soft nucleophile. Its lower in the periodic table and so its HOMO is larger and more spread out, this is important because orbital overlap plays a large role in Sn2, the electrophile not being charged.

Im pretty sure that acetate is not a strong enough base for E2. Are you sure that it cant be an Sn1 or E1 reaction?
