The video tutorial explains CIS-Trans nomenclature, focusing on geometrical isomerism. It covers the spatial arrangement of groups around carbon-carbon double bonds, using 2-butene as an example to illustrate CIS and Trans isomers. The tutorial also discusses geometrical isomers in cyclohexene, highlighting the stability of CIS isomers and the instability of Trans isomers in cyclic compounds. However, it notes that Trans isomers can exist in higher cycloalkenes like cyclodecene.
