Problem: Which attractive force is the weakest force between molecules? A. hydrogen bond B. covalent bond C. dispersion forces D. dipole-dipole attractions

FREE Expert Solution

We’re being asked to identify the weakest force 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
