The pair of species that has the same bond order in the following is:
Options
(a) O₂, B₂
(b) CO, NO⁺
(c) NO⁻, CN⁻
(d) O₂, N₂
Correct Answer:
CO, NO⁺
Explanation:
No. of elctrons in CO = 6 + 8 = 14
No. of elctrons in NO⁺ = 7 + 8 – 1 = 14
CO and NO⁺ are isoelectronic species. Isoelectronic species have identical bond order.
