Chemical topology

Definition

Chemical topology is a branch of chemistry that studies the geometric and topological properties of molecules, particularly focusing on how the arrangement of atoms and bonds affects a molecule's behavior and properties. This concept plays a vital role in understanding molecular knots and their classifications, as well as their implications for the structure and function of various chemical compounds.
