1.	Although both and are triatomic molecules, the shape of molecule is bent while that of is linear. Explain this on the basis of dipole moment.
Answer» nd in carbon dioxide is a polar bond hence there are two C=O bonds. Carbon dioxide MOLECULE has the zero- dipole moment. This can be POSSIBLE only if the molecule carbon dioxide BELONGS to the LINEAR molecule. The linear molecule of the carbon dioxide is given by O=C=O bond. The dipole moment of the two bonds C=O eliminate the moment of each other where water molecule has the moment of dipole (1.84D). Because of O-H the has a bent like structure which are adapted at an angle 104.5° and the moment of the bond do not get cancelled each other.
