Which Lewis structure of CO₂ is preferred?
A.O=C=O with zero formal charges
B.O–C≡O with O⁻ and C⁺
C.O=C=O with one lone pair on carbon
D.O=C–O with an unpaired electron
Explanation
Core Concept
The best structure minimizes formal charges and satisfies octets. Two double bonds give every atom zero formal charge, beating any single-triple arrangement that leaves +1/−1 charges.
Correct Answer
AO=C=O with zero formal charges
