CO_(2) " and " H_(2) Oboth are triatomic molecule but their dipole moment values are different. Why ? |
|
Answer» Solution :In `CO_(2)`, the dipole moments of TWO POLAR bonds (CO) are equal in MAGNITUDE but have OPPOSITE direction . Hence , the net dipole moment of the`CO_(2)` is , `mu = mu_(1) + mu_(2) = mu_(1) + (-mu_(1)) = 0 `. `{:(O = C = O),(" "to leftarrow),(" "mu_(1)"" mu_(2)):}` In this case `mu = mu_(1) + mu_(2)` ` = vec(mu_(1))+ (vec(-mu_(1))) = 0 ` Incase of water net dipole moment is the vector sum of`mu_(1) + mu_(2)` as shown. Dipole moment in water is found to be `1.85` D
