Why does boiling point of isomeric alkanes decrease with branching? Where you have isomers, the more branched the chain, the lower the boiling point tends to be. Van der Waals dispersion forces are smaller for shorter molecules and only operate over very short distances between one molecule and its neighbors. Which has more boiling point […]
