Topological indices are the numerical values that are connected to subatomic graphs in order to create the quantitative structure activity and structure attribute of a chemical compound and non-chemical graphs. The molecular structure of both chemical and non-chemical graphs is explained by topological indices. The goal of the current study is to determine M-polynomials, which will then be used to determine the degree-based topological indices of non-kekulean benzenoid hydrocarbons for n > ۱. For the non-kekulean benzenoid hydrocarbon, we determine the first K Banhatti index, modified first K Banhatti index, inverse sum index, randic index, symmetric index, harmonic index, first K Banhatti index, and K hormonic Banhatti index.
