Erich Hückel

Erich Hückel was a German theoretical chemist known for his contributions to the understanding of molecular systems, particularly in the study of conjugated compounds and aromaticity. In the 1930s, he developed the Hückel Rule, which helps predict the stability and energy levels of planar cyclic molecules, assessing whether they can be classified as aromatic. By applying mathematical techniques to molecular orbitals, Hückel provided valuable insights into the behavior of electrons in chemistry, influencing fields like organic chemistry and materials science, and laying foundational concepts for further research in molecular theory.
