Molecule AB has a bond length of 1.617  and a dipole moment of 0.38 D. The fractional charge on each atom(absolute magnitude) is: (e0=4.802×10-10 esu)
  1. 0.5
  2. 0.05
  3. 0
  4. 1.0

Solution

Assuming complete separation of charges (i.e. +e, -e on two ends)

μ=4.802×10-10esu×1.617×10-8 cm

=7.76×10-18 esu.cm=7.76 D

Fractional charge on dipole ends =0.387.760.05
