The dipole moment (μ) of HBr (a polar covalent molecule) is 0.817D (debye), and its percent ionic character is 12.1%. Estimate the bond length of the H-Br bond picometers.
•1 D = 3.34 x 10^-30 C • m and
• in a bond with 100% ionic character, Q = 1.6 x 10^-19 C.
Express your answer to two significant figures and include the appropriate units.
