Polarity

How does polarity affect boiling point and solubility? (please give example if possible)

Polar compounds have a higher boiling/melting point and are more soluble in water than nonpolar componds.

Polar molecules tend to have higher boiling/melting points because they have greater intermoleculr forces than nonpolar molecules do. Nonpolar molecules only have van der Waals forces acting between molecules., which is the weakest form of intermolecular force. Polar molecules have dipoles that give rise to stronget intermolecular forces, such as hydrogen bonding or dipole-dipole forces that make it harder to break apart.

The polarity of a molecule affects the boiling point because molecules that are higher in polarity usually have more electrons and thus require more energy in order to reach the boiling point.

If a molecule is more polar, it has more intermolecular forces since it has London dispersion forces and dipole-dipole and possibly more. Therefore, since it has more forces acting upon it, polar molecules tend to have higher boiling points.

Does anyone have a video they think is a good reference for this topic?
