Study Notes

Molecules can have partial positive and negative charges known as a dipole due to the distribution of charges within the molecule.
Polar covalent compounds can exhibit dipole-dipole interactions or hydrogen bonding, while nonpolar covalent compounds have only London dispersion forces.
Hydrogen bonding in molecules like H2O, HF, and NH3 leads to higher boiling points compared to other compounds in their groups.
Polarizability measures how easily the electron distribution of a molecule can be distorted.
Interactions between molecules can be ion-ion, ion-dipole, dipole-dipole, or London dispersion forces, depending on the types of compounds present.
