Explain how dispersion forces, dipole-dipole forces, and hydrogen bonds (intermolecular forces) affect the 2 states of matter using phase changes and heating curves.

What is the effect on vapor pressure with dispersion forces, dipole-dipole forces, and hydrogen bonds?

  • chemistry -

    I am not certain if I understand the question.

    vapor pressure indicates the tendency for molecules to move to the vapor state. If forces bind the molecules together, bp will be highter, and for a given temperature, vapor pressure is lower. If forces disperse molecules, bp is lower, and vapor pressure higher
