Problem

INTERMOLECULAR FORCES

Intermolecular forces (nonbonding forces) exist between molecules and influence the physical properties of the substance. The 5 most common intermolecular forces are:

1)  Ion-Dipole is the intermolecular force that exists between an ion and a polar compound. (Strongest)

Ex:   NaCl dissolved in H2O

 

2)  Hydrogen Bonding is the intermolecular force that exists when hydrogen is directly connected F, O, N. (2nd Strongest)

Ex:   NH3                                  H2O                  HF

 

3)  Dipole-Dipole is the intermolecular force that exists with polar covalent compounds. (3rd Strongest)

Ex: CHCl3               HCl                   HBr                  HI

 

4) Dipole/Induced-Dipole is the intermolecular force that exists when a nonpolar covalent compound interacts with a polar covalent compound. (4th Strongest)

Ex:       S8 (nonpolar solute) in  H2O (polar solvent)

 

 

5)  London Dispersion or Van der Waals Forces is the intermolecular force that exists with nonpolar covalent compounds. (Weakest)
