Question

Which of the following pairs have identical bond order?

Options

• \[\ce{O^{2-}_2}\] and \[\ce{F2}\]

• \[\ce{CO}\] and \[\ce{O^{2-}_2}\]

• F₂ and CO

• \[\ce{O^{2-}_2}\] and \[\ce{N2}\]

Answer 1

\[\ce{O^{2-}_2}\] and \[\ce{F2}\]

Explanation:

lsoelectronic molecules/ions have identical bond orders. Bond order of \[\ce{F2}\] and \[\ce{O^{2-}_2}\] is 1.
