The bond order in `O_2^+` is the same as in :

Options

A. `N_2^+`
B. `CN^-`
C. `CO`
D. `NO^+`

Answer

A

Explanation

Bond order of `O_2^+ = 1/2 [6 -1] =5/2`
M.O. configurration of `O_2`
` =sigma 1s^2 , sigma^(**) 1s^2 , sigma 2s^2 , sigma^(**) 2s^2 , sigma2p_x^2 , pi 2p_y^2 pi 2p_z^2`.
`pi^(**) 2p_y^1`
Bond order of `N_2^+ =1/2 [5-0] =5/2`
M.O. configuration of ` N_2^+ =`As given in sol ` 55.`
