45 b2 2- molecular orbital diagram

molecular orbital theory - Why is diboron (B2) paramagnetic? Before we get there it is worth while knowing a generic valence molecular orbital diagram where no s-p mixing occurs. This one pretty much applies to all main group elements heavier than nitrogen. This results in a triplet ground state. The finished valence molecular orbital diagram is pictured below. Tutorial on Chemical Bonding, Part 8 of 10 (Molecular orbitals) This second orbital is therefore called an antibonding orbital. This scheme of bonding and antibonding orbitals is usually depicted by a molecular orbital diagram such as the one shown here for the dihydrogen ion H2+.
