Does H20 have permanent dipole dipole forces as well as hydrogen bonding?

Answer 1

Yes, the permanent dipole-dipole forces in water are the hydrogen bonding forces.

Hydrogen bonding is a special case of dipole-dipole attractions.

It's just that these attractions are so much stronger than other dipole-dipole attractions that they get their own name: hydrogen bonds.

Yes, H2O (water) exhibits both permanent dipole-dipole forces and hydrogen bonding. The permanent dipole-dipole forces arise from the difference in electronegativity between the oxygen and hydrogen atoms, creating a permanent dipole moment. Hydrogen bonding occurs specifically in water molecules due to the strong attraction between the partially positive hydrogen atom of one water molecule and the partially negative oxygen atom of another water molecule.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
