Cyclobutadiene This molecule is cyclic, apparently fully conjugated, and planar. How many π electrons does it have? Answer: 4 (a double bond is made of 2 π electrons. There are two double bonds, therefore, 4 π electrons)
WebBenzene has 3 double bonds, so it has 6 π electrons. Aromatic Ions Hückel's Rule also applies to ions. As long as a compound has 4n+2 π electrons, it does not matter if the molecule is neutral or has a charge. For example, cyclopentadienyl anion is an aromatic ion. How do we know that it is fully conjugated? WebHow many pi electrons are there in benzofuran? This problem has been solved!

Benzofuran is the heterocyclic compound consisting of fused benzene and furan rings. This colourless liquid is a component of coal tar. Benzofuran is the "parent" of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants.
WebAntiaromaticity 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 ([4n+2] π electrons) and are highly stable, antiaromatic compounds are highly …
