The correct order of basicity of oxides of vanadium is:

Question

Canvas Classes · Accepted Answer

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:
