Although both and are triatomic molecules, the shape of the molecule is bent while that of is linear. Explain this on the basis of dipole moment.

Solution:
has a dipole moment of 0 according to experimental results. And it’s only possible if the molecule’s shape is linear, because the dipole moments of the C-O bond are equal and opposite, nullifying each other.
The dipole moment of is 1.84 D. Because the dipole moments of the O-H bond are unequal, the value of dipole moments indicates that the structure of the water molecule is bent.
