To draw the correct molecular orbital diagram, we first need to know the correct order of the molecular orbitals in terms of energy.
00:12
We'll have sigma 1s and sigma 1s star.
00:19
Then when we go to the second energy level, we've got sigma 2s and then sigma 2s star.
00:31
And then we go from there to pi 2p, and then from pi 2p, we go to sigma 2p, and then pi 2p star, and last of all, sigma 2p star.

Then we'll count the total number of electrons in c2, 2 minus, or actually just c2 minus.
01:20
Each carbon has six total electrons.
01:24
There are two of them, so that adds up to 12, plus the additional minus charge means we have 13 electrons...
