Molecular symmetry
In chemistry, 'molecular symmetry' is the symmetry of molecules. It also puts molecules into groups according to their symmetry. Molecular symmetry is a basic idea in chemistry. It can predict or explain many of a molecule's chemical properties, such as its dipole moment. Chemists study symmetry to explain how crystals are made up and how chemicals react. The molecular symmetry of the reactants help predict how the product of the reaction is made up and the energy needed for the reaction.
