Final answer:
The carbon atoms in CO₂ are sp hybridized, with a linear geometry due to the formation of two double bonds with oxygen.
Step-by-step explanation:
The orbital hybridization on the carbon atoms in CO₂ is sp hybridization. In CO₂, the carbon atom forms two double bonds with oxygen, resulting in a linear structure. This linear geometry means that the carbon atom uses two hybrid orbitals that are at 180° from each other, which are derived from one s orbital and one p orbital. The remaining two p orbitals are unhybridized and are used to form π bonds.
The orbital hybridization on the carbon atoms in CO₂ is sp for the central carbon atom, and sp³ for the terminal carbon atoms.
The orbital hybridization on the carbon atoms in CO₂ is sp for the central carbon atom, and sp³ for the terminal carbon atoms. Thus, for CO₂, the correct hybridization would be option A) sp.
