I could be getting this mixed up, so could someone please clear up the confusion. I know that increased branching is supposed to weaken Vanderwaals forces. It would make sense that this would decrease the mp since there are weaker intermolecular forces and hence not as high temp should be needed to break these weaker forces in going from solid to liquid. I swear EK says that it decreases bp and increases mp. Can someone confirm, does branching decrease or increase mp?
