In which pair is the stronger bond found in the first species ?

Options

A. `O_2^(-), O_2`
B. `N_2, N_2^(+)`
C. `NO^(+), NO^(-)`
D. `CO, O_2^(2+)`

Answer

BC

Explanation

Bond order :
(A)`O_2^(-)=(10-7)//2=105,O_2=(10-6)//2=2`
(B)`N_2=(10-4)//2=3,N_2^+ =(9-4)//2=2.5`
( C)`NO^+ =(10-4)//2=3, NO^(-) =(10-6)//2=2`
( D)`CO=(10-4)//2=3,O_2^(2+)=(10-4)//2=3`
