H2 Molecular Orbital Diagram

Then we rank them in order of increasing energy. The only orbitals that are important in our discussion of molecular orbitals are those formed when valence shell orbitals are combined.

Molecular orbital diagrams of diatomic molecules.

H2 molecular orbital diagram. Description of the molecular orbitals of the h2 molecule with an introduction to molecular orbital diagrams. Before we can draw a correlation diagram for b2 we must first find the in phase and out of phase overlap combinations for borons atomic orbitals. Molecular orbital mo theory of the h2 molecule.

Bonding mos antibonding mos and bond order. In order to predict the bond order molecular orbital diagram for h2 is to be drawn. This explanation is based on a mathematical model hence it is a theory.

The following slide illustrates the relative energies of the molecular orbitals compared to the original atomic orbitals. Ab a b gg with. Discussed in this video are.

Each boron atom has one 2s and three 2p valence orbitals. This tool is very well suited for simple diatomic molecules such as dihydrogen dioxygen and carbon monoxide but becomes more complex when discussing even comparatively simple polyatomic molecules such as methane. The molecular orbital diagram for an o 2 molecule would therefore ignore the 1s electrons on both oxygen atoms and concentrate on the interactions between the 2s and 2p valence orbitals.

Mo diagrams can explain why some molecules exist and others do not. Here is the result obtained for egs r via eq. Which ion has the stronger h h bond.

Molecular orbitals of h 2 the molecular orbital approach is one explanation for the ceh h bond. When two hydrogen atoms come closer then on combining two 1s orbitalstwo molecular. According to mot number of atomic orbitals combined is equal to total number of molecular orbitals formedelectronic configuration of h is 1s1.

πε and jr k r mr lr defined explicitly in atkins. Draw mo energy diagrams for the molecular ions h2 and h2. For example when two hydrogen atoms bond a σ1s bonding molecular orbital is formed as well as a σ1s antibonding molecular orbital.

Evaluate the ground state electronic energy based on this presumed approximate eigenfunction.
