13. Intermolecular forces

What are intermolecular forces?

The attraction of molecules/forces that cause this attraction

What are London dispersion forces?

The ability to create instantaneous dipoles at any moment

What is polarity?

What is polarizability?

The ability to create instantaneous dipoles and to respond to changing electric fields

Why is the surface area of a molecule important?

As the surface area increases, it allows for greater interactions between molecules

How does symmetry impact physical properties?

Less symmetrical, lower boiling point
More symmetrical, higher boiling point

What are dipole-dipole forces?

What is hydrogen bonding?

A very strong dipole-dipole attraction between electronegative atoms such as oxygen, nitrogen, fluorine

What is a hydrogen bond acceptor?

Electronegative atoms such as oxygens, nitrogen, or fluorine with a lone pair of electrons

What is a hydrogen bond donor?

Hydrogen atom covalently bonded to a fluorine, oxygen, or nitrogen
