Khan Academy: Electronegativity: Electronegativity and Intermolecular Forces

Chemists love London (dispersion forces)! Presentation begins with an explanation of intermolecular forces including hydrogen bonding, dipole-dipole attraction, and London dispersion forces. It also covers polarity and the relative...

Electronegativity is defined and compared to electron affinity. Trends based on groups and periods are also explored. [9:54]

Explanation of how differences in electronegativity effect chemical bonding. Bonds are classified by various bonding types.

Learn the difference between electronegativity and electron affinity. Group and period trends are also discussed in relation to atomic radii. [9:54]

The Pauling Scale is used to understand bonding due to electronegativity. Bond types are classified. [11:39]

Defines electronegativity and compares to electron affinity. Explains group and period trends in electronegativity using atomic radii. [9:53]

Explains what intramolecular and intermolecular forces are and the different types for each. Includes lots of examples.

Learn how to classify bonds as covalent, polar covalent or ionic by using the differences in electronegativity in this video. Video explains the Pauling scale to find the electronegativity differences in bonding. [11:38]
