Estimate the dipole moment, in Debye units, of the HI molecule based on difference in Pauling electronegativity between the atoms.
To estimate the dipole moment of the HI molecule based on the difference in Pauling electronegativity between the atoms, you can use the formula:
Dipole Moment (in Debye units) = 1.6 * (Electronegativity difference)
First, you need to find the electronegativity values for hydrogen (H) and iodine (I). According to the Pauling electronegativity scale, hydrogen has an electronegativity of 2.2 and iodine has an electronegativity of 2.66.
Next, calculate the electronegativity difference by subtracting the electronegativity of hydrogen from the electronegativity of iodine:
Electronegativity difference = 2.66 - 2.2 = 0.46
Finally, use the formula given above to calculate the dipole moment:
Dipole Moment (in Debye units) = 1.6 * 0.46 = 0.736 Debye
Therefore, the estimated dipole moment of the HI molecule based on the difference in Pauling electronegativity between the hydrogen and iodine atoms is approximately 0.736 Debye.
