The online dipole minute of CO2 molecule is zero. This is achievable provided that CO2 can be a linear molecule. (O=C=O). The bond dipoles of two C=O bonds cancel The instant of one another.
As a consequence of two lone pairs of electrons on O-atom, repulsion on bond pairs is larger in H20 in comparison to NH3 . As a result, the bond angle is considerably less in H20 molecules.
