Huckel’s Rule - Explanation of Huckel
Web20 aug. 2024 · Over a century, different aromaticity rules have been developed and validated. For planar monocyclic conjugated polyenes (also known as [ n ]annulenes), they will be aromatic if they contain [4 N + 2] π electrons according to Hückel's rule, or antiaromatic if they have [4 N] π electrons. WebCriteria for Aromaticity For a compound to be aromatic, it should fulfil all the given criteria. The compound should be cyclic, meaning its structure should form continuous rings. The … WebIn 1931, German chemist and physicist Erich Hückel proposed a theory to help determine if a planar ring molecule would have aromatic properties.
