MCQ
The oxidation state of phosphorus is maximum in_________.
- APhospine (PH3).
- BDiphosphine (P2H4).
- CMetaphosphoric acid (HPO3).
- DPhosphorus acid (H3PO3).
✓

- Metaphosphoric acid (HPO3).
Explanation:
The oxidation states of phosphorus in phosphine, diphosphine, metaphosphoric acid and phosphorus acid are −3, −2, +5 and +3 respectively. Hence, it is maximum in metaphosphoric acid.
