Question

Give me info on CO2, abo and bmo diagram, it acting as lewis acid

Answer 1

CO2 is linear due to sp hybridization of carbon. Lewis structure is O=C=O with lone pairs on O. MO theory: sp orbitals form sigma bonds, unhybridized p orbitals form pi bonds. Carbon is electron-deficient due to electronegative oxygens, acting as a Lewis acid. It accepts electron pairs from Lewis bases, e.g., $OH^-$, forming carbonate.

Answer 2

The Lewis structure of $CO_2$ is $:\ddot{O}=C=\ddot{O}:$. The carbon atom undergoes sp hybridization, leading to a linear molecular geometry. The molecular orbital theory describes the bonding in $CO_2$ as formed by the overlap of sp hybrid orbitals and unhybridized p orbitals on carbon with atomic orbitals on oxygen, forming sigma and pi bonds. Due to the electronegativity of the oxygen atoms, the carbon atom in $CO_2$ is electron-deficient and acts as a Lewis acid, capable of accepting electron pairs from Lewis bases like $OH^-$ to form species such as the carbonate ion ($CO_3^{2-}$).
