Möller's rule

Möller's rule is a mathematical guideline used in chemistry to determine the more stable isomer (a molecule with the same atoms but a different structure). It states that between two possible arrangements, the one with the lower overall energy—meaning less total energy stored in its bonds—is generally more stable. In simple terms, Möller's rule helps predict which molecule configuration is more likely to form and persist, based on energy considerations, guiding chemists in understanding molecular behavior and stability.
