1.	Linear form of carbon dioxide molecule has two polar bonds. Yet the molecule has zero dipole moment. Why?
Answer» Solution :(i) The linear form of carbon DIOXIDE has zero DIPOLE moment, even though it has two polar bonds. (ii) In `CO_2` there are two polar bonds [C =O], which have dipole moments that are equal in magnitude but have opposite direction (III) Hence the NET dipole moment of the `CO_(2)` is `MU= mu_1 + mu_2 = mu_1+(-mu_1)=0` (iv) `overset(O=)underset(mu_1)rarr overset(C)("") overset(=O)underset(mu_1)larr` (v)In this case, `mu=vecmu_1 + vec mu_2 = vecmu_1 + (-vecmu_1)=0`
