Biphenylene aromaticity
WebMay 20, 2016 · $\begingroup$ @Henry Pyrene is a fused-ring system which is why you need more sophisticated rules about aromaticity. That isn't needed here as the two … WebAntiaromaticity. Antiaromaticity is a chemical property of a cyclic molecule with a π electron system that has higher energy, i.e., it is less stable due to the presence of 4n delocalised (π or lone pair) electrons in it, as opposed to aromaticity. Unlike aromatic compounds, which follow Hückel's rule ( [4 n +2] π electrons) [1] and are ...
