Why, in liquid state, is H2O a London Force and hydrogen bonding. I understand why it is hydrogen bonding (FON) but why is it a London Force? Shouldnt it be hydrogen bonding and dipole-dipole interaction since hydrogen bonding is just a stronger dipole-dipole interaction?

Expert Answer

Step 1

All three kinds of intermolecular forces (Hydrogen bonding, dipole-dipole interaction and London force) are present between the water molecules.

Step 2

The attractive force that holds two molecules with help of the temporary dipole moment present in them is called as London force.
