We're just going to be looking at mo theory as well as our localized electron model, which is also known as our lowest structure.
00:07
So we've got the an ion c2 -2 -1.
00:09
So i've got it drawn up on the screen already is our lowest structure.
00:13
You can see that we've got a triple bond, which is made up of one sigma and two pi bonds there.
00:18
So it is an al -kind.
00:20
And we also have a full loan pair on each carbon.
00:25
So now i've drawn up my mo diagram as well.
00:29
So we can just go ahead and populate.
00:31
This so for each carbon we are donating four electrons four times two and then we need to add our two minus charge so we are adding in 10 electrons in total so we can go ahead and populate that in our two s and two p mo's one two three four five six seven eight nine ten so don't forget that you need to singly occupy and then doubly occupy your orbitals.
01:05
That's our filling rules.
01:07
And so now we can see that we have populated the entirety of our 2s, so we can neglect that in terms of bond counting, bond orders.
01:16
And now we can just look to our 2p, where we have six electrons in our sigma and pi bonding orbitals...
