Web3 sep. 2012 · Aromaticity The term aromaticity is used to describe aromatic compounds properties: • Highly stable. • Undergoes substitution reaction rather than addition reaction. • The C-C bond length (1.39Å), intermediate between single (1.47Å)& double (1.34Å) bonds. 10. WebHuckel’s Rule of Aromaticity :-. An aromatic compound must contain a cyclic and planer structure with (4n+2)π electrons Delocalizing effectively throughout the plane of the molecule. Thus, the Cyclic and planer compounds containing 2,6,10,14,18 etc., of π- electrons with effective Delocalization will have a aromatic character.

Web8 feb. 2024 · Huckel rule: The cyclic π molecular orbital formed by overlap of p orbitals must contain (4n + 2) p electrons, where n = integer 0, 1,2,3, … etc. Explanation: According to Huckel rule, a cyclic and planar compound is aromatic if it the number of π electrons is equal to (4n + 2), where n = integer 0, 1, 2, 3, … etc. e.g. Consider benzene molecule: WebIn 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, … smelly carpets after cleaning

WebAromaticity is defined as a property of the conjugated cycloalkenes which enhances the stability of a molecule due to the delocalization of electrons present in the π-π orbitals . In chemistry, aromaticity is a chemical property [1] of cyclic ( ring-shaped ), typically planar (flat) molecular structures with pi bonds in resonance (those ...
