What is the formal charge on each oxygen in CO₂ (two C=O double bonds)?
A.0
B.−1
C.+1
D.−2
Explanation
Core Concept
Each oxygen has 6 valence − 4 lone electrons − ½(4 bonding) = 0. Carbon also has zero, making CO₂ a neutral molecule with all-zero formal charges — the best Lewis structure.
Correct Answer
A0
