In molecular orbital theory, the electrons belonging to the molecule are placed in orbitals that extend all the - If the Bond Order is 1, then it is a single covalent bond. The higher the Bond Order, the more stable the molecule is. An advantage of Molecular Orbital Theory when it comes to Bond Order is that it can more accurately describe partial bonds (for example in H2 +, where the Bond Order = 1/2), than Lewis Structures.
