Question #7318a

Answer 1

Intermolecular forces are forces BETWEEN MOLECULES

1. Dipole-dipole (polar)
   Has a special case Hydrogen Bonds
2. London Dispersion (nonpolar)
3. Ion Dipole (ion and polar)

Answer 2

Intermolecular forces are forces that holds a molecule together.

Explanation:

Molecular compounds are able to display a wide range of physical properties due to the different intermolecular forces.

London Dispersion Forces - Weak forces which holds molecules together in solid, liquid and gas. These are cause by the temperary dipole movements of the molecule.

Dipole-dipole Forces - Occurs when the opposite ends of the molecule are attracted to each other. They are slightly stronger in comparison to London Dispersion Forces.

Hydrogen Bonding - Occurs when hydrogen is bonded to a highly electromagnetive atom (etc.N,O,F).
