Problem Details

The dipole moment (μmu) of HBr (a polar covalent molecule) is 0.790D (debye), and its percent ionic character is 11.7 % . Estimate the bond length of the H−BrNote that

  • 1 D = 3.34×10−30 C•m and
  • in a bond with 100% ionic character, Q = 1.6 × 10 − 19 C.

Express your answer to two significant figures and include the appropriate units.


Dipole moment

The dipole moment, μmu, of a bond can be calculated from the equation where QQ is the magnitude of the partial charges and rr is the bond length.
