WitrynaTo check whether a closed molecule has aromatic properties Huckel rule is used. This role also has the name Huckel’s rule of aromaticity. This rule was put forward by the physical chemist Erich Huckel in 1931. This rule is also called the 4n+2 rule or 4n 2 rule. According to this rule when a cyclic molecule obeys 4n+2 pi electrons it is aromatic.
