How can the bonding potential energy in a molecule with 2 or 3 atoms be calculated?

Using the equation: $V_{bonding} = rac{k_q imes q_1 imes q_2}{r}$

Using the equation: $V_{bonding} = k_e imes rac{q_1 imes q_2}{r}$

Using the equation: $V_{bonding} = rac{k_e imes q_1 imes q_2}{r^2}$ (correct)

Using the equation: $V_{bonding} = k_e imes rac{q_1 imes q_2}{r^2}$

How does the dielectric constant of the environment affect electrostatic or dipole-dipole interactions?

It decreases the strength of electrostatic or dipole-dipole interactions. (correct)

It increases the strength of electrostatic or dipole-dipole interactions.

It has no effect on electrostatic or dipole-dipole interactions.

It alters the nature of electrostatic or dipole-dipole interactions.

How can the van der Waals interactions be calculated?

Using the equation: $E_{vdW} = rac{A}{r^{6}} - rac{B}{r^{12}}$

Using the equation: $E_{vdW} = -rac{A}{r^{6}} + rac{B}{r^{12}}$

Using the equation: $E_{vdW} = -rac{A}{r^{12}} + rac{B}{r^6}$

Using the equation: $E_{vdW} = rac{A}{r^{12}} - rac{B}{r^6}$ (correct)
