Homework Help: Chemistry

Posted by Colby on Friday, December 15, 2006 at 3:14pm.

Arrange the following intermolecular attractions in order of increasing strengtgh:

Dipole interactions, dispersion forces, and hydrogen bonds.

dispersion forces, hyrdogen bonds then dipole interactions? is this right

Typical hydrogen bonds are about 15-20 kJ/mol and dipole-dipole bonds are about 4 kJ/mol; therefore, I would rank dipole-dipole in the middle. Hydrogen bonds actually are a form of dipole-dipole bonds but they usually are discussed separately and are exclusively called hydrogen bonds when H is attracted to N, F, or O.
