E / Z Isomers

In this video, we look at E / Z isomers. First we explore what is meant by E / Z isomers and how we can compare this to cis-trans isomers. We then look at how E / Z isomers can apply to alkenes with four different groups around the double bond. I then show you how to name E / Z isomers using the Cahn-Ingold-Prelog system (or CIP).
