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
H2O is dipolar, whereas BeF2 is not. It is because:
| 1. | H2O involves hydrogen bonding whereas BeF2 is a discrete molecule. |
| 2. | H2O is linear and BeF2 is angular. |
| 3. | H2O is angular and BeF2 is linear. |
| 4. | The electronegativity of F is greater than that of O |
Which of the following would have a permanent dipole moment?
| 1. | BF3 | 2. | SF4 |
| 3. | SiF4 | 4. | XeF4 |
