`CrO(O_(2))_(2)` is stable in pyridine. Explain?

The superoxide O_(2)^(-) ion is stable only in presence of :

Statements 1: Both CrO_(4)^(2-) and Cr_(2)O_(7)^(2-) ions when treated with acidified H_(2)O_(2) solution gives blue solution which turns green on standing. Statement 2: Blue solution of CrO_(5) is stabilised in the presence of organic solvent,e.g., ether, pyridine, etc.

What will the structure of CrO_(5) in presence of pyridine ?

What will the structure of CrO_(5) in presence of pyridine ?

The equilibrium Cr_(2)O_(7)""^(2-)hArr2CrO_(4)""^(2-) is shifted to right in-

In acidic medium, H_(2)O_(2) changes Cr_(2)O_(7)^(2-) ion to CrO_(5) . The oxidation states of Cr in Cr_(2)O_(7)^(2-) and CrO_(5) are respectively :

Assertion : Out of CrO_(3)& Al_(2)O_(3), CrO_(3) having lower melting point than Al_(2)O_(3) . Reason: Oxidation state of Cr in CrO_(3) is high
