Which of the following has the minimum bond length ?

Options

A. `O_2^-`
B. `O_2^(2-)`
C. `O_2`
D. `O_2^+`

Answer

D

Explanation

Bond order of `O_2^(+)=(10-5)/2=2.5`
Bond order of `O_2^(-) =(10-7)/2=1.5`
Bond order of `O_2^(2-)=(10-8)/2=1`
Bond order of `O_2 =(10-6)/2=2`
`because` Maximum bond order = minimum bond length
`therefore` Bond length is minimum for `O_2^(+)`
