Cis – Trans Isomers

In this video, we look at a special class of isomers called cis-trans isomers. First we explore why we can see cis-trans isomers in alkenes and how this is due to the double bond. We then look at the features that a molecule must show in order to have cis-trans isomers. Finally, we look at how to name cis-trans isomers and I give you examples to try yourself.
