Abstracts

We report relationship between molecular weights of some lower benzenoid hydrocarbons with other graph invariants called Randić index, harmonic index and π-electron energies of some benzenoid hydrocarbons. Based on these correlations we obtain relationship between molecular weights with Randić index, molecular weights with harmonic index, and molecular weights with energy of some lower benzenoid hydrocarbons and discussed which model is better among these three invariants.

Keywords :
