\mathrm{H} - X

bond length is

2.00 Å

and

\mathrm{H} - X

bond has dipole moment

5.12 \times {10^{ - 30}}\mathrm{C} - \mathrm{m}

, the percentage of ionic character in the molecule will be

View answer and explanation

Correct option: B

16\%

Option B is correct because the percentage of ionic character is calculated using the ratio of observed dipole moment to theoretical dipole moment.
