WebHowever, I think the easiest way to think a/b this question is that the last rxn takes place under thermo favored conditions, so the highest yield product is thermodynamically favored. There's also induction btw the methyl and isopropyl groups (b/c they're both on the same side) which adds to its stability. This last bit is more of a sanity check.
