As learnt in
Bond Order -
Bond order is defined as one half the difference between the number of electrons present in the bonding and the antibonding orbitals.
- wherein
Bond \:Order=\frac{N_{b}-{N_{a}}}{2}
In the given pair of species number of electron in NO^{+} = number of electron in CN^{-}= 14 electrons.
So they are isoelectronic in nature. Hence bond order of these two species will be also similar which is shown below.
NO+ and CN- has same bond order..
Option 1)
NO^{+}\: and \: CN^{+}
This option is incorrect
Option 2)
CN^{-}\: and \: NO^{+}
This option is correct
Option 3)
CN^{-}and \: CN^{+}
This option is incorrect
Option 4)
O{_{2}}^{-}and \: CN^{-}
This option is incorrect
