Hi there, let's start out by summarizing what type of molecule we get with certain bond types.
00:13
So bond type and molecule type.
00:17
I'm going to make two columns here, a little table, if you will.
00:22
So let's say the bond type in a molecule, let's say all of the bonds are non -polar.
00:30
If all the bonds are non -polar, the molecule type has to be non -polar.
00:36
It does not matter what its shape is or anything.
00:44
If all the bonds are non -polar, then the molecule has to be non -polar.
00:49
But let's say the molecule has polar bonds.
00:55
Then there are two options.
00:57
The molecule is going to be non -polar if it is symmetrical.
01:12
Or it will be polar if the molecule is asymmetrical.
01:24
In other words, when we have a polar, bond type, we need to know the molecular geometry to determine if the molecule is polar or non -polar.
01:38
Because we need to determine if it's symmetrical or asymmetrical...
