Abstract

Abstract Molecular topology is a key to determine the physiochemical aspects of the molecular structure. To determine the degree of irregularity of a certain molecular structure or a network has been a key source of interest for the molecular topologists as it provides an insight of the key features that are used to guess the properties of the structures. In this article, we are interested in formulating closed forms of irregularity measures of some popular benzenoid systems, namely, zigzag, rhombic, and honeycomb benzenoid systems. We also compared our results graphically and concluded that benzenoid system among above is more asymmetric than the others.

Highlights

  • Molecular topology is a key to determine the physiochemical aspects of the molecular structure

  • Benzenoid hydrocarbons have consistently attracted the attention of both chemists and pure mathematicians because of the structural complexities

  • Benzenoid systems are molecular structures having nice geometrical properties. These are constructed with a definite rule from a benzene molecule which is its fundamental building block
