Secondary Bonding (Van der Waals)
Fluctuating Induced Dipole Bonds Since the electrons may be on one side of the atom or the other, a dipole is formed: the + nucleus at the center, and the electron outside. Since the electron moves, the dipole fluctuates. This fluctuation in atom A produces a fluctuating electric field that is felt by the electrons of an adjacent atom, B. Atom B then polarizes so that its outer electrons are on the side of the atom closest to the + side (or opposite to the – side) of the dipole in A. This bond is called van der Waals bonding. Polar Molecule-Induced Dipole Bonds A polar molecule like H2O (Hs are partially +, O is partially), will induce a dipole in a nearby atom, leading to bonding.…
