What is the bond polarity of the water molecule?
The polarity of water can be calculated by finding the sum of the two dipole moments of both
For ionic compounds, the dipole moment could be calculated by:
For covalent compounds, the expression becomes:
For water, the partial charges are distributed as follows:
It is more complicated to calculate the partial charge on each atom, that is why I will skip this part.
The dipole moment of the
So the net dipole moment of water could be calculated by summing the two dipole moments of both
