Hi there.
00:03
This question is asking about hydrogen bonding.
00:06
In which of these molecules, we are likely to find hydrogen bonds.
00:14
Well, hydrogen bonding is, of course, an intermolecular force of attraction between molecules.
00:24
It's not an actual bond.
00:26
It's not an actual chemical bond, but it is an intermolecular force.
00:29
And we find it in molecules that are polar and have nitrogen to hydrogen, fluorine to hydrogen, or oxygen -to -hydrogen -covalent bonds.
00:57
So this is where we find hydrogen bonding, polar molecules that have n -h, f -to -h, or o -to -h bonds.
01:05
So let's look at our options here.
01:07
The first one is ch4.
01:09
So if we quickly sketch out its structure, we see that we have a non -polar molecule and it only has seed h bonds.
01:22
So that is not going to have hydrogen bonding.
01:26
Next we see hydrozine.
01:28
Hydrozine has two nitrogens bonded together.
01:33
Each of those hydrogens, or each of those nitrogen's rather, has two hydrogens on it.
01:44
And each nitrogen has a lone pair...
