Gas phase bond length and dipole moment of a compound (MX) is 3 Å and 10.8 D, respectively. The ionic character in gas phase MX is ____ % (Round off to one decimal place) \[ \left(1 \mathrm{D}=3.336 \times 10^{-30} \mathrm{C} \mathrm{m}\right) \]
Answer SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation Answer: 75.0 % — μ(100 % ionic) = e·r = 1.602 × 10⁻¹⁹ × 3 × 10⁻¹⁰ = 4.806 × 10⁻²⁹ C m = 14.41 D. Ionic character = 10.8/14.41 = 75.0 %.
