Which mechanism(s)would be favored under the following reaction conditions?

Question

Quizplus · Accepted Answer

The reaction conditions suggest a primary or secondary halide, which is compatible with E2 mechanism. E1 mechanism would require weaker nucleophile and a stronger acid, which is not indicated in the given conditions. S_N1 and S_N2 are both substitution reactions, not elimination reactions, so they are not favored under these conditions. A mixture of S_N1 and E1 is also not appropriate since they represent different reaction mechanisms.
