Well, melting points and boiling points reflect the degree of intermolecular force...

Explanation:

And certainly most organic compounds, whose formulae EXCLUDE heteroatoms, i.e. #O#, #N#, #X#, tend to have low to moderate normal melting and boiling points.

Throw in some polarity, especially the extreme polarity offered by intermolecular hydrogen bonding, and the boiling points elevate. Consider the normal boiling point of ethane, #-89# #""^@C#, versus that of ethyl alcohol, #+78.5# #""^@C#.
