What is bond order according to the Lewis theory? Write the structure and bond order of $H_2, O_2, N_2, CO,$ and $NO^{+}$.
(N/A) According to the Lewis theory of covalent bonding,the bond order is defined as the number of chemical bonds between two atoms in a molecule.
| Molecule and Structure | Bond Order |
|---|---|
| $H_2$ (dihydrogen): $H-H$ | $1$ |
| $O_2$ (dioxygen): $O=O$ | $2$ |
| $N_2$ (dinitrogen): $N \equiv N$ | $3$ |
| $CO$ (carbon monoxide): $C \equiv O$ | $3$ |
| $NO^{+}$: $[N \equiv O]^+$ | $3$ |
