Polarity in a molecule and hence the dipole moment depends primarily on electronegativity of the constituent atoms and shape of a molecule. Which of Does the following have the highest dipole moment? (i) CO2 (ii) HI (iii) H2O (iv) SO2

H2O

has a high dipole moment because Oxygen is highly electronegative.

This attracts the electron from Hydrogen towards it with greater charge.

Therefore,

H2O

has a high dipole moment.
