What is meant by the term bond order ? Explain ?
The stability of the molecule can be restated in terms of bond order.
A positive bond order (i.e. $\mathrm{N}_{\mathrm{b}}>\mathrm{N}_{\mathrm{a}}$ ) means a stable molecule.
A negative bond order (i.e. $\mathrm{N}_{\mathrm{b}}<\mathrm{N}_{\mathrm{a}}$ ) means on unstable molecule.
A zero bond order (i.e. $\mathrm{N}_{\mathrm{b}}=\mathrm{N}_{\mathrm{a}}$ ) means bond not possible.
