Physics - Electrostatics Question with Solution | TestHub

A polar molecular is a molecular 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 is non-zero. Hence,$H_{2}O$is a polar molecule while in all other cases the dipole moment are balanced, so the net moment is zero.
