Abstract
The problem of estimating physicochemical properties of chemical structures is a well-investigated problem in chemistry. A number of approaches have been proposed to solve this certain problem. One of these approaches is linked with molecular descriptors. The molecular descriptors that are defined in terms of connection numbers of adjacent vertices of the chemical graph of the considered chemical structure are known as bond incident connection (BIC) indices. The primary aim of this article is to study BIC indices of polyomino and benzenoid chains.
