Van der Waals Forces

  1. Feb 26, 2010 #1
    Is Van Der Waals forces just a name for all intermolecular forces that exist between molecules or does it only refer to certain types of intermolecular forces?

    All intermolecular forces.

    What about hydrogen bonds?

    van der Waals forces generally refer to intermolecular forces between two separate uncharged molecules (so this excludes covalent and ionic bonding). These forces include dipole-dipole interactions, dipole-induced dipole interactions, and induced dipole-induced dipole interactions (London dispersion forces). Although hydrogen bonds can be thought of as a class of dipole-dipole interactions, their properties are usually different enough that they are considered a class of intermolecular interactions separate from the van der Waals forces.
