Per NCERT §4.3.4 (bond order), which trio of N₂, CO, and NO⁺ have which property in common — and why?
AAll three are ISOELECTRONIC (14 e⁻) and have bond order 3
BAll bent
CAll ionic
DAll paramagnetic
Answer & Solution
Correct answer: A. All three are ISOELECTRONIC (14 e⁻) and have bond order 3
Per NCERT §4.3.4, N₂, CO, NO⁺ are isoelectronic species with bond order 3. F₂ and O₂²⁻ both have bond order 1.
