Question

state the kind of intermolecular forces between the molecules of water

Answer 1

is water polar or non polar?

Answer 2

polar

Answer 3

so it has a permanent dipole?

what about ionic interactions, does it have any?

Answer 4

No ionic interactions I think, and I'm not too sure about the dipole part. I don't really understand this whole thing

Answer 5

you're right, theres no ionic interactions (because the bond between O and H's is covalent).
If a molecule is considered polar, it means that the electronegativity different between the 2 atoms bound by the bond is greater than 0.4. The oxygen, since it's more electronegative than H has more electron density around it which gives it a partial negative charge \(\delta -\), similarly, H's get less electron density and so they have a partial positive charge \(\delta +\). There is a permanent dipole pointing towards the oxygen's lone pairs.
