Structure and Bonding
There is a table of various compunds, with their molar mass and melting point. I'm stuck on these questions:
-What intermolecular forces are present in liquid water and in liquid hydrogen selenide?
-Explain why the intermolecular forces are stronger in water than in the other compounds.
Any help would be greatly appreciated =)

Well, there are O-H bonds in water along with lone pairs of electrons, so there are hydrogen bonds in water. There's also both permanent and temporary dipole-dipole interactions, because oxygen is more electronegative than hydrogen, so the bond is polar. Same in hydrogen selenide, just no hydrogen bonds. I assume 
No idea what it is xD
Hydrogen bonds are a lot stronger than the other intermolecular forces. Each water has 2 hydrogens, as well as 2 lone pairs, so each can hydrogen bond to 2 others, which means the forces are stronger.
