The iodine bromide molecule (IBr) has a
bond length of 2.49 A° and a dipole moment
of 1.21 D. Calculate the effective charges
on the I and Br atoms in IBr in units of
electronic charge, e. (1D = 3.34 x 10 -3° C m,
electronic charge, e= 1.602 x 10 -19C)
Br has a charge of -0.101 and I has a charge of +0.101.
