It is found that mistaking and using characteristic group as functional group result in forming ir-rational naming rules and procedures. By taking characteristic group as a substituent producing functional group after substitution and correctly using these two groups in the nomenclature, modern substitutive nomenclature, characterized by the substitutive suffix, is formed. Modern substitutive nomenclature is more systematic and more versatile in naming organic compounds of various structures than the previous substitutive nomenclature without characteristic group in-volved.

The relationships between the stabilities of the C26N4 isomers and the sites where nitrogen atoms dope at the C30 cage have been discussed. The kinetic stability of C30(D5h), C26N4 isomers were examined by the minimum bond resonance energy (min BRE) model. The min BRE model results show that kinetic instability of these compounds are closely related to the existence of highly reactive substructures in the molecule.
