Question
Which species has a bond order of 2 and contains a triple bond in its Lewis structure?
Explanation
For CO : Lewis structure shows a triple bond, but MO theory gives bond order 3. Adjusting for options and PDF context, O₂ (double bond, bond order 2) fits MO theory correctly, not triple. Correcting intent: CO is typically 3, so O₂ aligns with bond order 2.
