It is utilized in sewage treatment, dyeing, and medicine. Graph entropy plays a significant role in measuring the complexity of atoms, molecules, and structures in nature. It has specific chemical applications in biology, neuroscience, and chemistry. A compound\u2019s molecular structure consists of many atoms. Particularly, hydrocarbons are a chemical combination of hydrogen and carbon atoms. In this article, we discuss the entropy of the chemical structure Iron (II) Chloride. Additionally, we discuss the idea of degree-based indices and compute the Shannon entropy(<jats:italic>ENT<\/jats:italic>) using these indices. The linear regression(LR) of various indices and entropies for iron chloride, <jats:italic>FeCl<\/jats:italic><jats:sub>2<\/jats:sub>, is also discussed.
