Although bothCO_2and H_2 O are triatomic molecules, the shape of H_2 O

1.	Although bothCO_2and H_2 O are triatomic molecules, the shape of H_2 O molecule is bent while that of CO_2 is linear. Explain this on the basis of dipole moment ?
Answer» Solution :`CO_2` is a linear in which the two C = are oriented in the opposite directions at an angle of `180^@`. The DIPOLE moment of C =0 is 2.3 D due to linear structure of `CO_2` the bond DIPOLES of two C = O bonds cancel with each other. Therefore resultant `mu`is zero. On the other HAND, `H_2 O` is polar molecule having dipole moment 1.54 D. Actually `H_2 O` molecule has BENT structure in which O-H bonds are oriented at an angle of `104^(0) 5^(1)` and dont cancel the bond moments of each other.
