The dipole moment μ of HBr (a polar covalent molecule) is 0.82 D (debye), and its percent ionic character is 12.1%. Estimate the bond length of the H-Br bond in picometers.
1 D = 3.34 x 10-30 C m and
in a bond with 100% ionic character q= 1.6 x10-19C
Also, dipole moment equation is mu=q*r
Please answer in picometers using 2 significant figures!
