Question

significance/applications of dipole moment.

Answer 1

The product of Magnitude of charge on either of the poles and distance b/w centre of positive and negative charges is called dipole moment.it is expressed in Debye
         1 Debye =3.33564x10power -30 coloumb meter
 applications
      ∞ it predicts the polarity of molecules
      ∞ it predicts the shape of the shape of molecules
     ∞it predicts the%ionic character of covalent bond
         

Answer 2

basically dipole is that the combination of two atoms or compound
1-it is vector quantity
2-its mainly depend on charge rather than length
3-LI-F has more polarising than LI-CL or any other halogen series . 
4-its mainly used to calculate which is more polarising....
