What is the bond order of B2?
Answer and Explanation: The bond order of B2 is 1.
Does Be2 exist?
From the electronic configuration it is clear that there is no singly filled atomic orbital present in beryllium. Without the half- filled orbital, the overlapping is not possible, therefore Be2 molecule does not exist.
What is the bond length of B2?
The equilibrium bond distance is 1.595 Å. At this bond distance, all 26 configurations contribute to the wavefunction. The most important are those, which describe two σ bonds between the two boron atoms.
Does h2 2+ exist?
4- Theoretically it would not be possible to form a molecule from two hydrides because the anti-bonding and bonding orbitals would cancel each other out. So, the bond order is zero. Because the antibonding ortibal is filled, it destabilizes the structure, making the “molecule” H22- very non-stable.
Is N2 +2 paramagnetic?
In fact, its highest energy occupied molecular orbital (HOMO) is its σ2pz bonding orbital, which currently contains two electrons. N+2 therefore involves the removal of one σ2pz electron. Thus, N+2 has a paramagnetic configuration due to the unpaired σ2pz electron.
What is the molecular orbital theory of octahedral complexes?
Molecular Orbital Theory of Octahedral Complexes. In contrast to crystal field theory, molecular orbital included the covalent nature of the metal-ligand bond interaction. No Metal- Ligand -bonding ( bonding only)
How is MO theory used to predict molecular structure?
MO Theory. • LCAO-MO Theory is a simple method for predicting the approximate electronic structure of molecules. • Atomic orbitals must have the proper symmetry and energy to interact and form molecular orbitals. • Photoelectron spectroscopy provides useful information on the energies of atomic orbitals.

What do you label a MO diagram with?
Label the MO diagram with the appropriate atomic orbitals on the metal, and the symmetry labels of the resulting MO’s. [Remember those orbitals which are symmetric with respect to an inversion center are labeled
