Solution

The formal charge on an atom in a molecule can be calculated using the formula:

Formal Charge = (Valence Electrons of Atom) - (Non-bonding Electrons + 1/2 Bonding Electrons)

For the oxygen atom in carbon monoxide (CO):

  1. Oxygen has 6 valence electrons.
  2. In the Lewis structure of CO, oxygen has 4 non-bonding electrons.
  3. Oxygen is involved in a triple bond with carbon, so it has 6 bonding electrons.

Substituting these values into the formula gives:

Formal Charge on Oxygen = 6 - (4 + 1/2 * 6) = 6 - (4 + 3) = -1

So, the formal charge on the oxygen atom in carbon monoxide is -1.
