Which of the following molecules is a polar molecule?

Options

A.
B.
C.
D.

Answer

D

Explanation

A ploar molecule is a molecule containing polar bonds , where the sum of all the bonds dipole moment is not zero.
In case of `H_(2)O`, the bonds are inclined at an angle so the net dipole moment in non- zero . Hence `H_(2)O` is a polar molecule while in all other cases the dipole moment are balanced , so that the net moment is zero.
