The correct order of basicity of oxides of vanadium is:
d & f-Block Elements · Class 12 · JEE Main Previous Year Question
The correct order of basicity of oxides of vanadium is:
- a✓
- b
- c
- d
Concept: Basicity of metal oxides decreases as oxidation state increases
| Oxide | V O.S. | Nature | |-------|--------|--------| | | +3 | Basic (most basic) | | | +4 | Amphoteric | | | +5 | Acidic (least basic) |
Rule: As oxidation state increases, the metal-oxygen bond becomes more covalent → oxide becomes more acidic (less basic).
Decreasing basicity:
Answer: Option (1)
