Question

A diatomic molecule has a dipole moment of 1.2D. If its bond distance is 1.0Å, what fraction of an electric charge exist on each atom? 

Solution

Correct option is

0.25

For 100% ionic character (for 1 Å bond length) 

, should besepreted by 1 Å  

  

                                   

                                  = 4.8 D

Now observed dipole moment = 1.2 D 

                                                 

                  

                                                   = 0.25.
