# How do we describe the hybridization in the carbon dioxide molecule?

The bonds in carbon dioxide, $C {O}_{2}$, may be considered purely covalent.
In terms of a valence bond description the carbon is $s p$ hybridized, and the oxygen atoms are each $s {p}^{2}$ hybridized. (It would be very worthwhile should you try to take the total number of valence electrons, $6 + 4 + 6$, and assign these 16 $e$ to particular atoms.
