Question

Which of the following have identical bond order?
(a) CN⁻
(b) $O_2^-$
(c) NO⁺
(d) CN⁺

Answer 1

i think b is correct .

Answer 2

HII BUDDY

HERE YOU GO

Number of electrons in O−2=2×8+1=17O2−=2×8+1=17

Number of electrons in NO+=7+8−1=14NO+=7+8−1=14

Number of electrons in Cs2=6+2×8=22Cs2=6+2×8=22

As CN−CN− and NO+NO+ are isoelectronic , both have same bond order.

Hence a is the correct answer.
