The bond length in an HI molecule is 1.61 Å and the measured dipole moment is 0.44 D. What is the magnitude (in units of e) of the negative charge on I in HI?
(1 debye = 3.34 × 10^-³⁴coulomb- meters; ; e=1.6 × 10^-¹⁹coulombs)

Question

The dipole moment (μ) is given by μ = q * d, where q is the charge and d is the bond length. Converting the dipole moment from Debye to coulomb-meters and the bond length from Å to meters, we can solve for q. The calculation gives q ≈ 0.057e.
