The electronegativity difference between all hydrocarbons is so small that we expect these molecules to be what?
Hydrocarbons consist of
For alcohols and amines, where the inclusion of the heteroatom introduces an atom that is substantially more electronegative than hydrogen, hydrogen bonding can operate to some extent with the result that the normal boiling points of methanol, ethanol, and methylamine are much greater than that of methane or ethane.......
The solvents with the higher normal boiling points also display substantial water solubilities. Why should this be so?
