What is bond order according to Lewis ? Write structure and bond order of ${{\rm{H}}_2}{\rm{,}}{{\rm{O}}_2},{{\rm{N}}_2},{\rm{CO}},{\rm{NO}}$.
What is bond order according to Lewis ? Write structure and bond order of ${{\rm{H}}_2}{\rm{,}}{{\rm{O}}_2},{{\rm{N}}_2},{\rm{CO}},{\rm{NO}}$.
In the Lewis description of covalent bond the Bond Order is given by the number of bonds between the two atoms in a molecule.
| Molecule | Structure |
Shared $e^{-}$pair |
Pondered |
| $\mathrm{H}_{2}$ (dihydrogen) | $H-H$ | $1$ | $1$ (single bond) |
| $\mathrm{O}_{2}$ (dioxygen) | $O=O$ | $2$ | $2$ (double bond) |
| $\mathrm{N}_{2}$ (dinitrogen) | $N \equiv N$ | $3$ | $3$ (triple bond) |
|
$\mathrm{CO}$ (carbon $\quad$ monoxide) |
$C \equiv O$ | $3$ | $3$ (triple bond) |
| $\mathrm{NO}^{+}$ | $(\mathrm{N} \equiv \mathrm{O})^{+}$ | $3$ | $3$ (triple bond) |
