A) Compounds have characteristic physical properties. How does their strength compare to covalent/ionic/metallic bonds? Some insects can walk on the surface of water without breaking through, as shown in the picture to the right. They are, however, strong enough to control physical properties such as boiling and melting points, vapor pressures, and viscosities. Not only are IMFs weaker than bonds-attractive forces due to simultaneous attraction for electrons that exist between 2 nuclei- but they also depend on the type of particle in a sample of matter⚛️. Oxygen and Nitrogen are both non polar molecules, so they have london dispersion forces (LDF). The only intermolecular forces between such molecules are weak van der Waals' forces. Boiling points are therefor more indicative of the relative strength of intermolecular. Unlike the other three gases, ammonia is a polar molecule and can hydrogen-bond, so it will experience stronger intermolecular attraction than the others.
