Question

Which of the following pairs have identical values of bond order?

• A. N2+ and O2+
• B. F2 and Ne2
• C. O2 and B2
• D. C2 and N2

Answer 1

Answer: (A)

N2+ and O2+

Answer 2

(1) Bond order of N2+ = 2.5 ;

The bond order of O2+ 1/2(10 – 5) = 2.5.

(2) Bond order of F2 = 1 ; The bond order of Ne2 = 0.

(3) Bond order of O2 = 2 ; The bond order of B2 = 1.

(4) Bond order of C2 = 2 ; The bond order of N2 = 3.
