The video tutorial explains the IUPAC nomenclature for cyclohexane derivatives using chair conformations. It covers naming strategies for compounds with different substituents, emphasizing alphabetical order and the importance of achieving the lowest possible numbering for substituents. The tutorial also distinguishes between cis and trans isomers based on the axial positions of substituents.
