Web24 okt. 2024 · Four Criteria for Aromaticity. The molecule is cyclic (a ring of atoms) The molecule is planar (all atoms in the molecule lie in the same plane) The molecule is fully conjugated (p orbitals at every atom in the ring) The molecule has 4n+2 π electrons (n=0 or any positive integer). Any compound that follows these criteria is an aromatic compound. In chemistry, aromaticity is a chemical property of cyclic (ring-shaped), typically planar (flat) molecular structures with pi bonds in resonance (those containing delocalized electrons) that gives increased stability compared to saturated compounds having single bonds, and other geometric or connective non-cyclic arrangements with the same set of atoms. Aromatic rings are very stable and … WebData were presented as mean ± standard deviation. A P-value of <0.05 was judged to be statistically significant. Results. Validation of GC/MS/MS assay.
