1 Intermolecular Forces Water is a polar molecule. It has an electric dipole strength of p = 6 x 10-30 C - m. This is roughly equivalent to a proton and an electron separated by a distance of d = 4 x 10-11 m (about the radius of a hydrogen atom). In this problem, we will use Coulomb's law to compare the force between two protons (H*), a proton and a water molecule, and two water molecules. Use the arrangement of the charges shown in the figure for your calculations. (a) r (b) (c) r (a) First, consider interactions at "short" distances. A chemical bond has a length on the order of r = 0.1 nm. • What is the force between two protons separated by a distance of r = 0.1 nm? • What is the force between a proton and a water molecule separated by a distance of r = 0.1 nm? What is the force between two water molecules separated by a distance of r = 0.1 nm? (b) Now consider a "long" distance: a separation of R = 1.0 nm. (This is about the length of ten hydrogen atoms lined up next to each…
