Give the structure of `CO_(2)` molecule.

Explanation

`CO_(2)` is a linear molecule. In this C atom undergoes `sp^(3)` hybridisation. Two `sp^(3)` hybridised orbitals of carbon atom overlap with two p orbitals of oxygen atoms. The hybridised orbitals of carbon atom form two sigma bonds. The unhybridised orbitals of carbon atom are involved in `p pi - p pi` bonding with oxygen atoms. The resonance structure of `CO_(2)` are as follows:
`:underset(..)overset(..)(O) - C -= overset(+)(O) : harr :overset(..)(O) = C = overset(..)(O): harr : overset(+)(O) -= C- underset(..)overset(..)(O):`
