All right, so we want to compare the boiling points of carbon monoxide, which has the following glue structure, and then carbon dioxide.
00:14
So we know that oxygen is more electronegative than carbon.
00:16
So if we were to draw the way that electrons are pulled with an arrow, then we'd have a situation like this.
00:23
And then for co2, we'd have one here and one here.
00:26
So these are dipoles that show the uneven distribution of electrons.
00:30
And here there's only one dipole pulling electrons all towards the oxygen.
00:33
So this molecule is polar.
00:37
For carbon dioxide, the dipoles cancel each other out because they point exactly opposite because you have a symmetrical lewis structure.
00:44
It's 180 degree bond angle.
00:45
It's linear.
00:46
So the oxygens are directly opposite each other.
00:49
So net non -polar...
