I wanted explain it using an MO diagram but it's a little difficult to write in this format. I'll just go through with how to construct it and the results. Firstly, note that the atomic orbitals of the Oxygen elements are of the same energy levels so we can draw them parallel with respect to the diagram: Orbitals

O O We can then draw in the electron configuration with respect to each individual atom. It follows that: Orbitals

2p _|_|_

2s _

1s _

Orbitals

2p +-|+-|_

2s +-

1s +- *where +/- indicates sign of coefficient of electron spin number* Now that the two atoms are interacting, the probability regions defined by Schrodinger's wave equation are altered and new "molecular" solutions/orbitals are defined. Because of the nature and behavior of waves, and by application of the photoelectric effect, different interactions lead to different consequences. If a wave is in phase with another wave they result in an increased amplitude: this gives electrons the most ideal energy position and may result in a decrease of energy over atomic configurations.

However, it also means that there will be times of destructive interference as opposed waves collide. This collision leads to nodes of complete interference and oppose the bonding of the elements. Such regions are known as anti-bonding orbitals. Now we can draw in our molecular orbitals and fill them according to the aufbau principle, where electrons will fill according to the lowest possible energy state. Also note that the 2pσ bond in Oxygen is the lowest in energy as it is larger than nitrogen.Anti-Bonding Orbitals denoted by * 2P :-

2pσ* 2pπ* 2pπ 2pσ

2S :- 2sσ* 2sσ

1S : -

1sσ* 1sσ

From 1sσ, the energy increases in each molecular orbital. Using both Oxygen atom's electrons we fill the orbitals. The diagram will have these results:

2P :-

2pσ* 2pπ* + +

2pπ +- +-

2pσ + -

2S :- 2sσ* +-

2sσ +-

1S : -

1sσ* +-

1sσ + -

The idea is that the electrons left 2 half filled degenerate orbitals. This makes Oxygen a diradical. If we now calculate the bond order to see which state the elements favor. Bond order is the half the difference of bonding electrons to anti-bonding electrons. Here we have (10 bonding - 6 anti-bonding)/2. 4/2 = 2. Therefore:

By molecular orbital Theory, the gas O2 is energetically favored to the elemental Oxygen and is of Bond order 2. It will have a double bond.

How is the molecular orbital digram of s2 look like?

The molecular orbital diagram for the diatomic sulfur molecule (S2) shows the arrangement of molecular orbitals formed from the atomic orbitals of the two sulfur atoms. The diagram includes bonding and antibonding orbitals, with the lower energy σ(1s) and σ(1s) orbitals, followed by the σ(2s) and σ(2s) orbitals. For the valence p orbitals, the diagram features two degenerate π(2p) bonding orbitals, followed by a higher energy σ(2p) bonding orbital, and their respective antibonding orbitals. In total, S2 has 12 valence electrons, filling the bonding orbitals and contributing to its stability.


Why air is diatomic?

Air is primarily composed of nitrogen (N2) and oxygen (O2) molecules. Both nitrogen and oxygen are diatomic molecules, meaning they naturally exist in pairs (N2 and O2) due to their electron configuration and bonding tendencies. This is why air is considered diatomic.


What is the Molecular orbital theory diagram for co?

The molecular orbital diagram for CO shows the formation of sigma and pi bonding orbitals. The diagram would illustrate the mixing of carbon's 2s and 2p orbitals with oxygen's 2s and 2p orbitals to form molecular orbitals. The diagram would also show the bond order and relative energies of the bonding and antibonding orbitals in CO.


What two kinds of bonding molecular orbitals?

The two kinds of bonding molecular orbitals are sigma (σ) and pi (π) orbitals. Sigma orbitals are formed by the head-on overlap of atomic orbitals and are characterized by cylindrical symmetry around the bond axis, allowing for strong bonding. Pi orbitals, on the other hand, are formed by the side-to-side overlap of p orbitals and have a nodal plane along the bond axis, resulting in weaker bonding compared to sigma orbitals. Together, these orbitals play a crucial role in determining the stability and properties of molecules.

Why non bonding orbitals do not participate in LCAO?

The question does not make sense. LCAO takes a linear combination of atomic orbitals from the atoms, some orbitals are not energetically favourable to produce bonds (*other exclusions are symmetry) and these do not form bonding orbitals.

What is the difference between non-bonding and antibonding orbitals in molecular chemistry?

Non-bonding orbitals are electron orbitals that do not participate in bonding between atoms, while antibonding orbitals are electron orbitals that weaken or oppose the formation of chemical bonds between atoms.

Does oxygen is a diatomic molecule?

Oxygen is a diatomic gas.


Is oxygen stable before bonding?

Oxygen is a stable gas in its elemental form, as O2. It is a diatomic molecule that is highly stable because of the strong covalent bonds between the two oxygen atoms.


What is the difference between bonding and anti bonding molecular orbital?

Electrons in a bonding orbital have lower energy levels than the average energy of a valence electrons in the isolated atoms between which the orbital is formed. Antibonding orbitals do not meet this criterion, so that anitbonding orbitals can be stable only in conjunction with bonding orbitals, whereas bonding orbitals can be formed without any accompanying antibonding orbitals.The molecular orbitals which is formed by the addition of atomic orbitals is called bonding molecular orbitals.The molecular orbitals which is formed by the subtraction of atomic orbitals is called antibonding molecular orbitals.
