Molecular Orbital Diagram Of B2
Bo 1 2 bonding e anti bonding e 1 2 8 4 2 lcao mo theory also predicts correctly that o2has two unpaired electrons. 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.
Mo Diagrams For Diatomic Molecules
Interm of orbitals of similar symmetry and energy.
Molecular orbital diagram of b2. Give bond order and predict whether they are diamagnetic or paramagnetic for all the molecules above question 1 3. A molecular orbital diagram or mo diagram is a qualitative descriptive tool explaining chemical bonding in molecules in terms of molecular orbital theory in general and the linear combination of atomic orbitals lcao method in particular. Each boron atom has one 2s and three 2p valence orbitals.
A mo is defined as the combination of atomic orbitals. Molecular orbitals the region an electron is most likely to be found in a molecule. I drew a diagram of b2 in which i filled both bonding and anti bonding orbitals of 2s sigma and 2s sigma.
Draw molecular diagram of h2 b2 and n2. A number of valence electrons of each boron atom 3in the formation of b2 molecule three valence electrons of each boron atom ie. Then we rank them in order of increasing energy.
I also calculated the bond order of this molecule to be 32. Additionally i labelled the humo as pi2py and the lumo as sigma2px. This was on a quiz and i somehow got the bond order and the lumo indicated wrong.
Molecular orbital diagrams of diatomic molecules. Whats the different between the mo diagram of all the above molecules from question 1 compared to o2 and f2. As well i filled in the sigma 2px and pi 2py orbits.
Homonuclear diatomics molecules consisting of two identical atoms are said to be homonuclear diatomic such as. H 2 n 2 o 2 and f 2. Molecular electron configuration for o2 σ2σ2σ2π4π2 we can also calculate the oo bond order.
6 in all have to be accommodated in various molecular orbitals in the increasing order of their energies. A brief introduction to molecular orbital theory duration.
