Although both CO_2 and H_2O are triatomic molecules.,the shape of H_2O molecular is bent while that of CO_2 is linear. Explain these on the basis of dipole moment.

1.	Although both CO_2 and H_2O are triatomic molecules.,the shape of H_2O molecular is bent while that of CO_2 is linear. Explain these on the basis of dipole moment.
Answer» SOLUTION :Experimental measurement has shown that the DIPOLE moment of `CO_2` is zero. This is possible only if `CO_2` is linear molecule. The two BOND DIPOLES cancel each other giving it a net dipole moment value of zero.
