The dipole moment of

{HBr}

2.60 \times 10^{-30} {~cm}

and the interatomic spacing is

1.41 \mathop {\text{A}}\limits^ \circ

. What is the percent ionic character of

{HBr}

View answer and explanation

Correct option: B

11.5 \%

Option B (11.5 %) is correct because the percent ionic character is calculated by dividing the observed dipole moment by the calculated dipole moment and multiplying by 100.
