Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Species having the same bond order are (1) \[N_{2}^{2-}\] (2) \[N_{2}^{+}\] (3) \[{{N}_{2}}\] (4) \[N_{2}^{-}\]A) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: C
Solution :
BO of \[N_{2}^{2-}=\frac{1}{2}(10-6)=2\] BO of \[N_{2}^{+}=\frac{1}{2}(9-4)=2.5\] BO of \[{{N}_{2}}=\frac{1}{2}(10-4)=3\] BO of \[N_{2}^{-}=\frac{1}{2}(10-5)=2.5\] Hence, bond order of\[N_{2}^{+}\]and\[N_{2}^{-}\]are same.
