Carbon dioxide CO2 is a linear molecule with a carbon atom double-bonded to two oxygen atoms O=C=O . The bond between carbon and oxygen is a polar covalent bond, specifically a double bond, which consists of one sigma bond and one pi bond.The bond strength of a molecule can be estimated by considering the bond dissociation energy BDE , which is the energy required to break a bond homolytically. The BDE values for carbon-oxygen single C-O and double C=O bonds are approximately 358 kJ/mol and 745 kJ/mol, respectively. Since CO2 has two C=O double bonds, its bond strength is relatively high.However, it's important to note that predicting the exact bond strength of a molecule requires more advanced computational methods and experimental data. The given values are approximate and can vary depending on the specific molecular environment and other factors.
