Cyclopentadienyl

In organic chemistry, cyclopentadienyl is a cyclic group of atoms with the formula C₅H₅. Cyclopentadienyl are closely related to cyclopentadiene. Cyclopentadienyl have five carbon atoms bonded together in a pentagonal planar ring, all five of which are bonded to individual hydrogen atoms. Cyclopentadienyl is chemically aromatic and shows equal bond lengths between carbon atoms in the ring.
