Which of the following contains more than one peroxy linkage?
Options:
Answer:
Solution:
The question asks which of the following compounds contains MORE THAN ONE peroxy linkage. A peroxy linkage is an -O-O- bond. We need to examine the structures of the given compounds.
A. H₂SO₅ (Caro's acid): This molecule has the structure HO-O-SO₂-OH. It contains ONE peroxy linkage.
B. H₂S₂O₈ (Marshall's acid): This molecule has the structure HO-SO₂-O-O-SO₂-OH. It contains ONE peroxy linkage.
C. H₄P₂O₈: This molecule has the structure (HO)₂P(O)-O-O-P(O)(OH)₂. It contains ONE peroxy linkage.
D. CrO₅: This compound has a unique butterfly structure. It contains ONE oxide linkage (Cr=O) and TWO peroxy linkages. The structure can be visualized as a central chromium atom (Cr), double-bonded to one oxygen atom (O), and with two peroxy groups (-O-O-) attached to the chromium.
Therefore, the compound containing more than one peroxy linkage is CrO₅.
