Bond energies in NO, NO+ and NOā are such as
We know that,
→ Its harder to break a triple bond than a double and single bond.
⇒ Bond order ∝ Bond energy
Lets take a look at the bond order of these species.
You will learn to calculate the following in the section "Molecular Orbital Theory". For now, let us just make a note of these bond orders shall we?
⎧⎪⎨⎪⎩NO−⇒2NO+⇒3NO⇒2.5⎫⎪⎬⎪⎭
Therefore, bond energies will be in the order of
NO+> NO> NO−
