Supplementary Problem 7 (revised)

The interhalogen compound IF_{3} is calculated to have
a dipole moment of 2.48 D. When used with the ideal VSEPR
model, the measured dipole moment can provide an estimate of the
dipole moment of the fluorine-iodine bond. __Draw__ the
complete, preferred Lewis structure for IF_{3}. Double
check that your electron count is correct and then show the __calculation__
of the dipole moment of the fluorine-iodine (FI) bond from the
dipole moment of the entire molecule assuming no angular
distortions. In calculating dipole moments here, the
effect, if any, of lone pairs on the dipole moment magnitude may
be neglected.
