Electric Dipole

Which of the following molecules is a polar molecule?

Show answer and solution

Answer: (d)

$H_2$ , $O_2$ and $CO_2$ (linear) are symmetric, so their dipole moment is zero.
$H_2O$ is bent: centres of positive and negative charge do not coincide, so it is polar.
So the answer is (d) $H_2O$ .
