1.

Compare the relative stability of following species and indicate their magnetic properties : O_2 , O_(2)^(+),O_2 ^(-) ,(superoxide), O_(2)^(-2) (peroxide)

Answer»

SOLUTION :Bond orders of different species are:
`O_(2)-2.0,O_(2)^(+)-2.5,O_(2)^(-)-1.5,O_(2)^(-2)-1.0`
Relative STABILITY `O_(2)^(+)gtO_(2)gtO_(2)^(-)gtO_(2)^(-2)`
Magnetic PROPERTIES `O_(2)^(+)` is para `O_(2)` is para,
`O_(2)^(-)` para `O_(2)^(-2)` is DIA
