Find the total number of oxy acid which do not contain linkage (where )
H₄P₂O₆ (hypo phosphoric acid), H₃P₃O₉, H₂S₂O₈, H₂S₂O₆, H₂S₂O₃, H₂S₂O₄
Answer:
Solution:
The question asks to identify the number of oxyacids from the given list that DO NOT contain an X-X linkage, where X can be S, P, or N.
Let's analyze each compound:
1. H₄P₂O₆ (Hypophosphoric acid): Contains a P-P linkage.
2. H₃P₃O₉ (Cyclic metaphosphoric acid): Contains P-O-P linkages, but no direct P-P linkage.
3. H₂S₂O₈ (Peroxodisulfuric acid): Contains an O-O (peroxo) linkage, but no direct S-S linkage.
4. H₂S₂O₆ (Dithionic acid): Contains an S-S linkage.
5. H₂S₂O₃ (Thiosulfuric acid): Contains an S-S linkage.
6. H₂S₂O₄ (Dithionous acid): Contains an S-S linkage.
The oxyacids that do not contain an X-X linkage (P-P or S-S) are H₃P₃O₉ and H₂S₂O₈.
Therefore, the total number of such oxyacids is 2.
