Respuesta :

carbon monoxide atoms have two different ions Cu + and Cu2 + .such atoms do not obey the octet rule .

thats it :)..
Carbon has four electrons and oxygen has six. If only one bond were to be formed between C and O, carbon would have five electrons and oxygen 7.To complete the carbon and oxygen octets in CO, we must employ a triple bond.Even though there is no completion of octet rule.
