WebSep 24, 2024 · Cyclopentadiene Ion. One of the most well know examples of an aromatic ion is the 1,3-cyclopentadiene ion. 1,3-Cyclopentadiene is nonaromatic due to the … WebThis is induced by orbital symmetry (HOMO of the cyclopentadiene and LUMO of the ketene), and the necessity to attack the p-orbitals from opposite sides of the ketene. The animations visualize the molecular rearrangement and the orbital symmetry (basis set of atomic p-orbitals, not molecular orbitals) of this concerted cycloaddition.
WebMolecular Orbitals of Cyclopentadienyl. Cyclopentadiene is an acidic molecule due to the high stability of its conjugate base (C 5 H 5–) due to the conjugate base being aromatic. The 6 π electrons cause cyclopentadienyl to be aromatic and they also act as a pentahapto ligand allowing it to bind by all 5 carbons.
