In carbon dioxide CO2 , there are two carbon-oxygen double bonds. The molecule has a linear structure with the carbon atom in the center and the two oxygen atoms on either side. Each carbon-oxygen bond consists of one sigma bond and one pi bond.The bond order is the number of chemical bonds between a pair of atoms. In CO2, the bond order of the carbon-oxygen double bond is 2, as there are two bonds one and one bond between the carbon and each oxygen atom.The bond length is the distance between the nuclei of two bonded atoms. The bond length of the carbon-oxygen double bond in CO2 is approximately 1.16 angstroms , which is shorter than a carbon-oxygen single bond approximately 1.43 but longer than a carbon-oxygen triple bond approximately 1.08 . This is because double bonds are stronger and pull the atoms closer together compared to single bonds, while triple bonds are even stronger and pull the atoms even closer.
