The dipole moment of compound AB is 10.92 D and that of compound CD is 12.45 D. If the bond length of AB is 2.72 A° and that of CD is 2.56 A°, then for these compounds the correct statement is:
| 1. | More ionic nature in AB | 2. | More ionic nature in CD |
| 3. | Equal in both | 4. | Cannot be predicted |
