Question

Identify the correct resonance structures of carbon dioxide from the ones given below:

• A. $O=C=0$
• B. $O-C\equiv 0$
• C. $O^{-}-C\equiv O^{+}$
• D. $O^{-}\equiv C-O^{+}$

Answer 1

Answer: (A), (C)

$O^{-}-C\equiv O^{+}$

Resonating structures of carbon dioxide :

● $C{O}_2$ has a total $16$ valence electrons and has three resonating structures.

● The $C$ atom in $C{O}_2$ undergoes sp hybridisation.

● The resonance structures are shown below



● Thus, structure given in Option $B$ and Option Dare resonating structures of $C{O}_2$ .
