WebJan 28, 2024 · In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties. His rule states that if a cyclic, planar molecule has 4 n + 2 π electrons, it is considered aromatic. This rule would come to be known as Hückel's Rule.
