Chemistry for 16 - 18 year olds: Structure of Benzene.

Description
One of several hundred video-tuitions in high school chemistry, available at www.20to9.com Here we look at the overlapping of orbitals in ethane, ethene and benzene. In so doing, we touch upon hybridization - both sp3 and sp2. Paper models are used to attempt to show the 3 dimensional arrangement of orbitals and how they overlap. While hybridization will not be examined, I believe that it is necessary to cover it to some extent in order to distinguish between the sigma and pi bonds making up a 'double bond' and to account for the delocalisation of electrons in benzene. Don't watch this if you fall into the category - "just tell me what I need to know to pass".
