Answer» Correct Answer - a The linear triatomic moulas of the type B-A-B e.g. `CO_(2)` have no dipole moment not because the individual `C = O` bonds are non- polar but because the two bond moment (polarity) cancel each other .Therefore , gemoetry of molecule can be predicted by the value of dipole moment .
