Final answer:
The bond order of CO is 2, which means there is a triple bond between the carbon and oxygen atoms.
Step-by-step explanation:
The bond order of CO is 2. In CO, there is a triple bond between the carbon and oxygen atoms. The bond order is determined by the number of bonds between two atoms in a molecule. A single bond has a bond order of 1, a double bond has a bond order of 2, and a triple bond has a bond order of 3.
The bond order is calculated by counting the number of bonding electrons and dividing it by 2. In the case of CO, there are 4 bonding electrons, resulting in a bond order of 2.
The incorrect statement in the solution given is that the bond order of CO is ~2.6. The correct bond order is 2, as explained above.
