In carbon dioxide CO2 , there are two carbon-oxygen double bonds. The bond order of a carbon-oxygen double bond is 2, as there are two shared electron pairs between the carbon and oxygen atoms.The bond length of a carbon-oxygen double bond in CO2 is approximately 1.16 angstroms or 116 pm picometers . This value can vary slightly depending on the specific molecule and its environment, but 1.16 is a commonly accepted value for the bond length of a C=O double bond in CO2.
