Dipole-dipole Shapes and Molecular Dipoles When a molecule has a dipole we call it a polar molecule. Hydrogen bonding is a special case of dipole-dipole interaction with a significant increase in strength. London dispersion forces increase the larger the atomic size. This leads to larger dipoles being established. For nonpolar The electrostatic attraction between oppositely charged ends of polar molecules are called dipole-dipole interactions, (as illustrated in Figure $9. Unlike hydrogen bonding or dipole-dipole interactions, LDFs arise from **temporary For Br₂, these forces are **exclusively London dispersion forces (LDFs)**, a type of **van der Waals force**. A molecule such as CO 2 contains polar bonds, but due to their arrangement, the individual dipoles cancel out to make the overall molecule nonpolar. Substances with covalent The presence of this dipole can, in turn, distort the electrons of a neighboring atom or molecule, producing an induced dipole.
