In this question we've been given two compounds and we've been asked to explain their difference in the melting points.
00:08
So what is important to note about the melting point is we are changing phase from the solid phase to the liquid phase.
00:15
And we are doing this by breaking intermolecular forces of attraction that will be existing between the solid molecules.
00:25
So what determines the melting point is the strength of these intermolecular forces.
00:31
The stronger they are, it means we're going to need more energy to break them, which means we are going to need a higher mp, that is the melting point is going to be higher because we need more energy and a higher temperature to break those intermolecular forces.
00:48
Now looking at the compound that we've been given here, the first one, the first one can form intra -intramolecular, intramolecular forces, intramolecular hydrogen bonds.
01:02
So these are intramolecular because these are hydrogen bones that are forming within the molecule itself.

We have the n -o -2 group, the n -o -2 group...
