The dipole moment of hydrogen chloride bond distance: 127 pm is 1.03 D. The per cent ionic character of its bond is about

The per cent ionic character of its bond is about 17.

The Percent ionic character is found by the formula as,

              $=\frac{\left(1.03\times 3.3356\times {10}^{-30} \mathrm{Cm}\right)}{\left(1.602\times {10}^{-19} \mathrm{kg}\right)\left(127\times {10}^{-12} \mathrm{m}\right)}\times 100=16.9\mathrm{\%}$

Hence Percent ionic character is 17.
