Question: How many pi electrons are there in benzofuran?

WebBenzofurans, alternatively known as coumarone or benzo[b]furan, are heterocyclic compounds having fused benzene and furan rings. Benzofurans are compounds with a … 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? bishop stopford term dates 2023
