In this question you are assigned with the task to give the molecular orbital energy level diagram for three molecules, c2, c2, c -o, and o2.
00:11
First, let us provide a mo diagram for carbon.
00:15
Molecular orbitals are given in red color.
00:20
Onus orbital of two carbons combine to give sigma 1s, sigma 1s, sigma star 1s.
00:27
In similar way, 2s also combines to give sigma 2s.
00:32
Sigma star 2s there are 3 suborbital in 2p all the 12 electrons is filled in m -o there is no unpaid electrons therefore there is no magnetic movement for c2 molecule and bond order is it is number of electrons in bonding orbitals minus anti -bonding divided by 2 there is 8 electrons in bonding orbitals and 4 electrons in anti -bonding therefore bond order is in similar way let us calculate for oxygen molecule as well.

Everything is same except the fact that the sigma 2p z will come down and it is followed by pi 2 p y and 2 p x and then it is pi star 2 p y and pi star 2 p x and finally come sigma star 2 p z.

Number of electrons in 2 p orbital orbital or so...
