The electronegativity difference between N and F is greater than that between N and H yet the dipole moment of NH3 (1.5 D) is larger than that of NF3 (0.2 D). This is because:
| 1. | In NH3 as well as in NF3 the atomic dipole and bond dipole are in the same direction |
| 2. | In NH3 the atomic dipole and bond dipole are in the same direction whereas in NF3 these are in opposite directions |
| 3. | In NH3 as well as in NF3 the atomic dipole and bond dipole are in opposite directions |
| 4. | In NH3 the atomic dipole and the bond dipole is in opposite directions whereas in NF3 these are in the same directions |
Which of the following represents the oxidation states of phosphorus in H4P2O5, H4P2O6, H4P2O7, respectively?
| 1. | +3, +5, +4 | 2. | +5, +3, +4 |
| 3. | +5, +4, +3 | 4. | +3, +4, +5 |
The incorrect statement regarding oxoacids of phosphorus is:
| 1. | Orthophosphoric acid is used in the manufacture of triple superphosphate. |
| 2. | Hypophosphorous acid is a diprotic acid. |
| 3. | All oxoacids contain tetrahedral four coordinated phosphorus. |
| 4. | All oxoacids contain at least one P=O unit and one P-OH group. |
Which of the following compounds does not release oxygen when heated?
1. Zn(ClO3)2
2. K2Cr2O7
3. (NH4)2Cr2O7
4. KClO3
The strong reducing behaviour of H3PO2 is due to:
1. Presence of one -OH group and two P-H bonds.
2. High electron gain enthalpy of phosphorus.
3. High oxidation state of phosphorus.
4. Presence of two -OH groups and one P-H bond.
