Which sequence correctly describes a relative bond strength, of oxygen molecule, superoxide ion and peroxide ion?

Options

A. `O_2ltO_2^(-)ltO_2^(2-)`
B. `O_2gtO_2^(-)gtO_2^(2-)`
C. `O_2ltO_2^(-)gtO_2^(2-)`
D. `O_2^(-)gtO_2 gt O_2^(2-)`

Answer

B

Explanation

Bond strength depends on bond order. More is B.O more is the strength
B.O of `O_2` =2 , B.O of `O_2^-` =1.5 , B.O of `O_2^(2-)`=1.0
