If the bond length and dipole moment of a diatomic molecule are 1.25 ~A and 1.0 D respectively, what is the per cent ionic character of the bond?

Options

  1. A10.66
  2. B12.33
  3. C16.66
  4. D19.33

Correct answer

C. 16.66

Step-by-step solution

experimental = Dipole moment 10⁻¹⁸ theoretical = Bond length 4.8 10⁻¹⁰ 10⁻⁸ esu cm Per cent ionic character = _ experimental _ theoretical 100= 1.0 10⁻¹⁸ 100 1.25 4.8 10⁻¹⁰ 10⁻⁸ =16.66 %
