#Unit 1. Molecules and their Interaction Relevant to Biology

Choose the correct statement regarding the Spontaneous dipole - induced dipole interaction 

1. Spontaneous dipole - induced dipole interaction are also known as dispersion or London forces related to orientation effect.

2. The potential energy of an induced dipole-induced dipole interaction is depending on the first ionization energy of the molecule

3. Spontaneous dipole - induced dipole interactions are large networks of intermolecular forces between nonpolar and non-charged molecules and atoms (i.e. alkanes, noble gases, and halogens)

4. In Spontaneous dipole - induced dipole interaction a small increase in the radius, would greatly decrease the potential energy of the interaction.
