Question

Why does branching leads to lower surface area?

Answer 1

branching leads to lower surface area because as more num of branches are grown it would resultantly lessen the impact on space

Answer 2

This is due to the weaker Van der Waals dispersion forces betweenbranched organic molecules compared to straight chain molecules. ... Weaker intermolecular forces means that less energy is required to separate the molecules of a compound from its liquid surface, thus lowering the boiling point.
