Attractive Intermolecular Interactions

Postby Haley Dveirin 1E » Tue Nov 12, 2019 8:37 pm

If a question asks you to identify the types of attractive intermolecular interactions that might arise between molecules of a substance (for example NH2OH) how do you know which ones? The answer for NH2OH is dipole-dipole and induced dipole-induced dipole but how do you know?

There are always induced dipole-induced dipole forces between molecules. There will be dipole-dipole forces if both molecules have dipoles and are oriented with the positive side near the other molecule's negative side. There will be hydrogen bonding if a H is bonded to a O, F, or N and it can interact with a lone pair of electrons in a nearby molecule.
