London dispersion forces are a type of intermolecular force. They are relatively weak. They are also called induce-dipole induce-dipole interactions. 1  Present in non-polar molecules.  Due to non-systematic electron distribution where one molecule induces a dipole on another molecule.
INTERMOLECULAR FORCES AND BONDING. The forces holding molecules together are generally called intermolecular forces. there are strong bonds such as covalentor ionic bonds and weak bonds such as dipole-dipole interactions the London dispersion force and hydrogen bonding covalent bondã ionic bond ãH bond ãdipole-dipole forces âLondon forces.
