WebFor which reaction mechanisms—SN1, SN2, E1, or E2—of thefollowing statement true? A statement may be true for one or moremechanisms. Tertiary (3°) alkyl halides react faster than 2° or 1° alkyl halides. WebFor our next problem, we have a secondary alkyl halide. So, just looking at our reactions, we can't really rule any out here. So, all four are possible, until we look at our reagent. Now, we saw in an earlier video, that DBN is a strong base, it does not act like a nucleophile. So SN1 and SN2 are out. And a strong base means an E2 reaction.
