![]() Explain CO2 Lewis structure in simple words However, if CO 2 is dissolved in water it becomes carbonic acid which is a weak acid. Is Carbon dioxide acidic or basic?Ĭarbon dioxide is not an acid itself, since it does not contain ions of hydrogen (H +). In case you have any questions related to this blog, please feel free to comment. There are three resonance structures for CO2 as shown in the figure.įollowing are some of the frequently asked questions. Delocalized electrons that cannot be described by a single Lewis formula with an integer number of covalent bonds can be described via resonance structures. Resonance Structure for CO2Ī combination of two or more Lewis structures that together represent the delocalization of electrons in a single polyatomic ion or molecule is known as a resonance structure. The formal charge on CO 2 is zero, that’s why CO 2 is not negative or positive. Half of the bonded electrons in central Oxygen =4/2 =2 electrons Unbonded electrons in central oxygen = 4 electrons Valence electrons in central oxygen = 6 electrons. ![]() Half of the bonded electrons in carbon =8/2 =4 electrons Unbonded electrons in carbon = 0 electrons Valence electrons in carbon = 4 electrons
