Question

Which of the following pairs of species have the same bond order ?
A. `O_(2),NO^(+)`
B. `CN^(-),CO`
C. `N_(2),O_(3)^(-)`
D. `CO, NO`

Answer 1

Correct Answer - d
Species which have same no of e s have same bond order
Total no of electron in CN is `14`
Total no of electron in CO is also`14`
Hence B O of Both CN & CO is `3`
