2020年5月30日 — In 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties.
2023年12月7日 — Equally important is the number of π electrons, which, according to molecular orbital theory, must be equal to 4n + 2, in which n = 1, 2, 3, etc ...
2020年6月1日 — According to Huckel's Rule, all planar Aromatic Compounds must have 4n+2 pi-electrons where n is an integer (i.e. n= 0, 1, 2, 3, 4…etc.). This ...
Aromatic compounds contain 4n+2 π electrons, where n is a whole number starting from 0. This is called the Hückel's rule discovered by Erich Hückel in 1931.
2012年6月29日 — It is a formula that tells you what numbers are in the magic series. If your pi electron value matches any number in this series then you have ...
