 Chemical graph theory

Chemical graph theory is a branch of mathematics that applies graph theory concepts and techniques to solve problems in chemistry. It involves representing chemical compounds as graphs, where atoms are represented as vertices (nodes) and chemical bonds are represented as edges (connections between vertices). This representation allows for the analysis of the structure and properties of chemical compounds using graph-theoretical methods. Key aspects of chemical graph theory include: 1. **Molecular Structure Representation**: Different types of molecules can be represented as graphs.
