Understanding Alkenes and Functional Groups

The video tutorial explains how to name alkenes by identifying the longest carbon chain and determining the position of double bonds. It covers the identification of functional groups and their priority using the Cahn-Ingold-Prelog system. The tutorial also differentiates between 'entgegen' and 'zusammen' configurations based on the position of higher priority groups around the double bond, using examples of hept-3-ene and oct-3-ene.
