So for this question, we're asked to arrange each of these compounds in decreasing polarity.
00:08
So first, let's look at the bond polarity of each of these compounds.
00:12
So in the first one, right, we have hydrogen bonded to oxygen.
00:17
So we're going to have a hydrogen bond, which is a very strong bond.
00:23
Next, we have hydrogen bonded to nitrogen, which is also a hydrogen bond with strong polarity.
00:31
And then last, we have the carbon bonded to carbon and then carbon bonded to hydrogen.
00:40
So if you look, this is a very symmetrical molecule.
00:46
And so there's going to be no polarity because the electronegativity values cancel each other out.
00:53
There's no dipole moment.
00:54
So this is going to be a non -polar bond...
