We are given three different molecules and we have to arrange them in order of increasing surface tension as a fixed temperature.
00:07
And also we'll explain the ranking.
00:10
So the one with the lowest surface tension will be our c .h3, c2 .o .h.
00:17
And then we will have our h -o -c -h -h -c -h -2 -o -h.
00:24
The last one, we have h -o -c -h -c -2 -o -h and c -h -2 -o -h.
00:32
All right, so the surface tension, essentially, we are looking at how strong the molecules being held together at the service.
00:42
So we are also looking at the strength of the intermolecular interaction, so from here, we can see that the intermolecular interaction among all three of them will be hydrogen bonding.
00:55
Okay, so if we have a stronger intermolecular interaction, which means that the molecule in the liquid can hold attract to each other much more strongly, so we have a stronger surface tension...
