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…

How do intermolecular forces determine the physical properties of a molecule?
Which of the following molecules has the higher AHvap (the amount of energy needed to change the substance from a liquid to a gas) and why? A They both have the same Hvap, because they have the same type of intermolecular force. AHvap is temperature dependent, so it depends on the temperature. A, because it has stronger intermolecular forces, requiring more energy to overcome the intermolecular forces. B, because it has stronger intermolecular forces, requiring more energy to overcome the intermolecular forces. Not enough information is given.

If you place a container of a mixture of liquid water and water vapor (the system) on a hotplate: When the hotplate temperature is above 100 °C what change will occur in the system? Name the process. Draw a molecular level representation of the change as the thermal energy is added during this process. Be sure to label the strongest intermolecular force and use a dashed line (- - -) to distinguish it from covalent bonds.
