So the molecular orbital energy diagram for co, we're told to use the one for o2.
00:06
It looks something like this.
00:08
We've got sigma, sigma star, and then we have sigma and pi.
00:20
And finally, we have our pi star and our sigma star.
00:26
And these stars indicate that they're anti -bonding orbitals.
00:32
So now we need to know how many electrons to put in this.
00:35
Oxygen has six, carbon has four, so altogether we need to put ten electrons in.
00:46
And i'm going to fill them from the bottom first.
00:49
That's one, two, three, four, five, six, seven, eight, nine, ten.
01:00
Like that.
01:02
So i've drawn anything that's bonding in common.
01:05
Green and then it's anti -bonding in red...
