What do you mean by 'how do you do it ?'.
You have to be more specific if you want any constructive help or people will be simply put off by the ambiguous nature of your questions.

Hydrogen Bonds.

Water has two hydrogens while HF has only one. So, obviously the water will make multiple bonds (three) and when together then form a greater intermolecular force than that of HF, since HF can form hydrogen bonds with only two other atoms.

The Points on line depict Carbon atoms. If it is just a change of line means Carbon-Hydrogen atoms. If Chlorine or smth else is there then it must be specified.
