Our 2nd Annual Scheuermann's Disease Fundraiser on the afternoon of Sunday October 4th has now been posted to the VisitPitsburgh website. ... VisitPittsburgh is a website designed to help people plan their next visit to Pittsburgh, PA.
An antibonding orbital is a molecular orbital containing an electron outside the region between the two nuclei. As two atoms approach each other, their electron orbitals begin to overlap. This overlap forms a molecular bond between the two atoms with its own molecular orbital shape.
In this case, it is still close to a d orbital in energy, location, and shape. When orbitals on two different kinds of atoms combine, the bonding orbital is considered to be more like the orbital that was initially at lower energy. Suppose a ligand has more than one lone pair on the donor atom.The donor atom could share an extra pair of electrons with the metal, to form a double bond. This type of interaction is called pi-donation, because a pi bond is formed (not to be confused with sigma donation from a pi bond, as in alkene binding).ome ligands can accept a pair of electrons from the metal. An example is a carbonyl complex, which has a C=O pi antibonding orbital that can interact with a d orbital. a) Show the antibonding orbital on the carbonyl (CO) ligand. b) Show how a metal d orbital can interact with this orbital.
