The video tutorial explains the E&Z terminology for alkenes, highlighting the limitations of cis and trans terms for tri- or tetra-substituted alkenes. It introduces the Con Ingold Prelog convention to assign priority to substituents on each carbon of a double bond, allowing for the determination of E (opposite sides) or Z (same side) configurations. The tutorial provides examples to illustrate the process and offers a mnemonic to remember the E&Z meanings.
