Question

The dipole moment of LiH is  and the interatomic distance between Li and H in this molecule is 1.596Å. What is the per cent ionic character in LiH?

Solution

Correct option is

76.8%

The dipole moment of 100% ionic molecule (Li+H)

      = (1 electronic charge) (interatonic distance) 

     

       

Fractional ionic character  

     

     

      = 0.768 

The bond in LiH is 76.8% ionic.
