Does Co2 Have Resonance Structures
1 Answer 1
$\begingroup$
It is most always possible to draw resonance structures. In example of $\ce{CO2}$ you could imagine a resonance construction in which the carbon doesn't take an electron octet and a positive charge and 1 of the oxygen atoms conveying a negative charge.
Y'all could also draw one in which the carbon is just connected via a single bound to each oxygen and conveying two positive charges while the two oxygens carry a negative charge each.
Yous might come up with more of those structures.
Then the question y'all really wanna ask is whether these resonance structures accept any existent contribution to the bodily bonding state of $\ce{CO2}$ and for that you will run into that all of the described strucutures are highly unfavourable due to their energetic country. Therefore the normal Lewis-notation of $\ce{CO2}$ decribes the real bonding state pretty well as all other resonance structures don't contribute much.

$\begingroup$ I'm merely confused. There was an IB chemistry exam that asked for which of the following compounds have resonance structures. However, information technology said that CO2 did not count as a compound having resonance structure. $\endgroup$

$\begingroup$ The they virtually likely meant resonance construction that actually contribute to the structure and bounding state of the molecule. In that example (as mentioned above) CO2 does indeed not take a resonance structure. $\endgroup$
