It is calculated by taking the difference between the number of bonding electrons and the number of antibonding electrons, and dividing by two.<\/p>\n<p>In the case of carbon monoxide, there are four bonding electrons (two from the carbon atom and two from the oxygen atom) and two antibonding electrons. Therefore, the bond order is $\\frac{4-2}{2} = 2.5$.<\/p>\n<p>Option A is incorrect because it does not take into account the antibonding electrons.
