The dipole moments of diatomic molecules AB and CD are 10.41 D and 10.27 D, respectively, while their bond distances are 2.82 and 2.67 , respectively. What does this indicate? [Electronic charge (q) = 4.8 × 10-10 esu]
  • a)
    Bonding is 100% ionic in both the molecules.
  • b)
    AB has more ionic bond character than CD.
  • c)
    AB has less ionic bond character than CD.
  • d)
    Bonding is nearly covalent in both the molecules.
Correct answer is option 'C'. Can you explain this answer?

The dipole moments of diatomic molecules AB and CD are 10.41 D and 10...
Dipole moment of AB molecule when the bond between A and B is 100% ionic
= q × d (charge × distance)
(electronic charge) q = 4.8 × 10-10 esu
d = distance in cm.
= 4.8 × 10-10 esu × 2.82 × 10-8 cm
= 13.536 × 10-18 esu cm
= 13.536 D
[D = Debye unit of dipole moment:
1D = 10-18 esu-cm]
Actual dipole moment of AB molecule
= 10.41D
% age ionic character
=
= 76.9%
Similarily, dipole moment of CD molecule when the bond is 100% ionic,
= q x d = 4.8 x 10-10esu × 2.67 × 10-8 cm
= 12.816 × 10-18esu-cm = 12.816 D
Actual dipole moment of CD molecule = 10.27 D
% ionic character =
So, we can say that AB is less ionic than CD.
