Hi there.
00:04
In this question, we have the cl2 co molecule.
00:09
And we want to discuss the hybridization of the carbon atom, as well as the sigma and pi bonds in this molecule.
00:18
That means the best thing we can do first is to draw out a lewis structure.
00:23
So let's go ahead and do that.
00:24
To determine our lewis structure, we need to know how many valence electrons we're working with.
00:29
So there are two chlorines.
00:31
Each chlorine.
00:32
Each chlorine.
00:32
Is a halogen, so there are seven valence electrons in each chlorine.
00:36
So that means two times seven, plus we have one carbon.
00:41
There are four valence electrons in the carbon, and then we have one oxygen, which contains six valence electrons because it's in group six a.
00:51
Adding these together gives us 24 valence electrons.
00:57
And in our lewis dot structure, valence electrons are represented as dots.
01:03
So we need to have exactly 24 dots in our structure.
01:08
Carbon is going to be in the center, and the chlorine will be on two of the sides, while the oxygen is on a third side.
01:19
We know we have to have at least a single bond holding these all together.
01:25
So i'm going to draw in single bonds using six of my valence electrons.
01:29
Remember two electrons make a covalent bond.
01:33
Then i'm going to go start completing octets.
01:37
I'm going to start with my terminal atoms, so the ones on the outside.
01:41
So completing chlorine octet, completing the other chlorine octet.
01:48
I've used 18 dots so far.
01:50
There's 1920, 21, 22, 23, 24.
01:56
All right, i am out of dots.
01:58
The carbon does not yet have an octet.
02:02
Well, each chlorine has seven valence electrons and tends to only make one covalent bond.
02:08
So it is most likely that oxygen is going to be the element that would form a double bond with the carbon.
02:18
All right, so this is what we have here.
02:20
We can write this more as a structural formula and show its geometry a little bit better by writing it like this.
02:32
This is the same structure that our diagram depicts.
02:37
I've just gone ahead and am showing its geometry.
02:41
A little better.
02:44
All right.
02:45
So first thing we want to talk about is the hybridization of the carbon...
