 Forces that occur between molecules.  Intramolecular forces are the forces that bond atoms together to form compounds and diatomic molecules. They are much stronger forces than Intermolecular Forces (IMF) 10.1 Copyright © Houghton Mifflin Company. All rights reserved. Chapter 10 | Slide 2

 Dipole = areas of partial charge within a molecule due to the difference in electronegativity of the bonded atoms.  Molecules with dipole moments can attract each other electrostatically  The positive area of one attracts the negative area of the other.  Physically arranged so + and – are aligned.  Only about 1% as strong as covalent or ionic bonds Copyright © Houghton Mifflin Company. All rights reserved. Chapter 10 | Slide 3

 Instantaneous dipole that occurs accidentally in a given atom induces a similar dipole in a neighboring atom.  Significant in large atoms/molecules.  Occurs in all molecules, including nonpolar ones Copyright © Houghton Mifflin Company. All rights reserved. Chapter 10 | Slide 4
