Dipole-dipole forces occur between molecules that have permanent net dipoles. This means that the molecule must be polar.

A) N2 - Nitrogen is a diatomic molecule, meaning it consists of two nitrogen atoms. Since they are the same element, they share electrons equally and there is no dipole moment. So, N2 does not exhibit dipole-dipole forces.

B) Ne - Neon is a noble gas and exists as individual atoms, not molecules. Therefore, it does not exhibit dipole-dipole forces.

C) H2O - Water is a polar molecule because the oxygen atom is more electronegative than the hydrogen atoms, creating a net dipole. Therefore, H2O does exhibit dipole-dipole forces.

D) CCl4 - Carbon tetrachloride is a tetrahedral molecule and the dipole moments of the C-Cl bonds cancel each other out, making the molecule nonpolar. Therefore, CCl4 does not exhibit dipole-dipole forces.

E) CO2 - Carbon dioxide is a linear molecule and the dipole moments of the C=O bonds cancel each other out, making the molecule nonpolar. Therefore, CO2 does not exhibit dipole-dipole forces.

So, the only substance in the list that will exhibit dipole-dipole forces is H2O.
