Problem

Which term represents an intermolecular force in a sample of pure water? 

A) hydrogen bonding 

B) covalent bonding 

C) metallic bonding 

D) ionic bonding

Solution

Intermolecular forces are forces between molecules. 


Recall that there are several types of intermolecular forces (IMF):

1. Ion-dipole interaction– occurs between an ion and a polar covalent compound; strongest IMF

2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F; 2nd strongest IMF

3Dipole-dipole interaction– occurs between two polar covalent compounds; 3rd strongest IMF

4. Dispersion forces – occurs in all compounds and is the primary IMF exhibited by nonpolar compounds; weakest IMF
