Question

How many of the following species have bond order of `2.5` ?
`N_(2)^(o+)` (ii) `N_(2)^(Theta) ` (iii) `O_(2)^(o+)` (iv) `O_(2)^(Theta)` (v) `NO` (vi) `CN` .

Answer 1

Correct Answer - 5
For (i) `N_(2)^(o+)` and (ii) `N_(2)^(Theta)`
` For (iii) O_(2)^(o+)` and (iv) `O_(2)^(Theta)`
For (v) `NO` and (vi) `CN`
Hence, `n_(2)^(o+),N_(2)^(Theta), O_(2)^(o+) NO` and `CN` have bond order` =2.5` .
