Which mechanism is favored by the reaction of a secondary alkyl bromide with potassium t-butoxide?

Question

Quizplus · Accepted Answer

The reaction of a secondary alkyl bromide with potassium t-butoxide will typically favor an elimination reaction due to the bulky and strong base, which can cause steric hindrance in a substitution reaction. This makes options A, B, and D less likely. Option C is also less likely since secondary alkyl halides typically undergo elimination reactions via the E1 or E2 mechanism. Between E1 and E2, E2 is favored by the use of strong bases, such as potassium t-butoxide, and secondary alkyl halides. Therefore, the best choice is E.
