The dipole moment of L i H is 1.964 × 1 0 - 29 Coulomb meter and the interatomic distance between L i and H…

The dipole moment of LiH is 1.964×10-29 Coulomb meter and the interatomic distance between Li and H is 1.596 Å. The percentage ionic character of LiH is
  1. 82.5%
  2. 63.2%
  3. 76.8%
  4. 90.5%

Solution

δ=1.964×10-291.596×10-10=1.2306×10-19C
%ionic character=1.2306×10-19×1001.602×10-19=76.8% .
