In this video, we have some molecules here.
00:02
We want to select the ones in which hydrogen bonding is possible.
00:07
So that means that we need to have a direct bond between h and o, h and n, or h and f.
00:16
If there's, you know, both oxygen and hydrogen, but they're not directly bonded, that doesn't count.
00:21
They have to be connected to each other in order to create that really strong dipole that will allow for the hydrogen bonding.
00:28
All right.
00:29
So we have ch3 -cho.
00:31
We see that we do have an o and an h, but they're both connected to carbon, not to each other.
00:36
So no hydrogen bonding here.
00:37
So i'll put a red x.
00:39
All right.
00:40
Ch2, f2.
00:41
So we have hydrogens and fluorines, but they're not directly bonded.
00:44
They're all bonded to the carbon as this ball and stick model shows...
