In (QSAR)/(QSPR) studies, topological indices play an essential role, as a molecular descriptor. For measuring the structural information of chemical graphs and complex networks, the graph entropies with topological indices take the help of Shannon’s entropy concept, which now become the information-theoretic quantities. In discrete mathematics, biology, and chemistry, the graph entropy measures play an essential role. In this paper, we study the Boron Nanotube and we compute entropies of these structures by making relation of newly defined degree based topological indices, called Sombor index with the help of the information function, which is the number of vertices of different degrees together with the number of edges among the various vertices. Further, the numerical and graphical comparison are also studied.
