How does the structure of a molecule affect the amount of intermolecular forces it has. For example, a more linear structure might increase forces and Hydrogen bonds might do the same. Thanks!
Structure of a molecule - If you have any lone electron pairs, it's going to make your molecule polar.
If your molecule is polar, then it automatically has dipole-dipole forces with other molecules of that substance.
Structure of a molecule - if you have hydrogen directly attached to an F, O, or N atom, then you will automatically have hydrogen bonding going on between those substance's molecules.
