Solution: 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)

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)
