Bonding in Alkenes
This video looks at the formation of pi and sigma bonds that make up the bonding in alkenes.
Pi Bonds in 15 Seconds
A simple concise explanation of what a pi bond is.
Stereoisomerism
This video uses molecular models to explain stereoisomerism and describes the different types of stereoisomers.
Explaining the Lack of Rotation in the C=C Bond
This video highlights how the bonding in alkenes results in the lack of rotation in the C=C bond.
