ANSWERS TO MOLECULAR ORBITALS PROBLEM SET 1. Determining Bond Order: Molecular orbital (MO) theory is one of two theories used to explain the real-life physical parameters, shapes, and bonds in covalent molecules. The bond order according to this model would be 1, as the σ electrons would not contribute to the bonding. According to Molecular Orbital theory, only those molecule can exists which have net positive bond order while the molecules with negative or. In its most basic form, the bond order is the number of bonded electron pairs that hold two atoms together. Draw the molecular orbital diagram for ne2 and determine if the bond between the two atoms. This situation is similar to the C 2 case, except that in B 2 the π u orbitals are half filled, leading to an even weaker π bond than in the C 2 case. The addition of two more electrons to make Ne2 fills all the bonding and antibonding MOs. The bond order of any given molecule can be calculated from the difference of the electrons of bonding orbitals and electrons of antibonding orbitals. the molecular orbital bond order is calculated as 1/2[x-y] where x is the number of electrons in _____ molecular orbitals and y is the number of electrons in ____ molecular orbitals.
