WitrynaIntermolecular Forces . Intramolecular forces (bonding forces) exist within molecules and influence the chemical properties. Intermolecular forces exist between molecules and influence the physical properties. We can think of H 2 O in its three forms, ice, water and steam. In all three cases, the bond angles are the same, the dipole moment is the … Witryna15 lis 2013 · Consequently, the boiling points of the branched chain alkanes are less than the straight chain isomers. The above extract from my book, mentions clearly that branching makes the molecule more compact and thereby decreases the surface area. Even for isomeric alkyl halides, the boiling points decrease with branching.
