A Level Chemistry Revision "Polar Bonds and Polar Molecules".

You can find all my A Level Chemistry videos fully indexed at www.freescienc...
In this video, we look at how bonds can be polar or non-polar. I take you through the idea of bond polarity in terms of electronegativity. We then look at the two ways to show that a bond is polar. We then explore how a molecule can have an overall polarity (dipole moment) and why certain molecules are non-polar even when they have bond polarity.
This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification.
