Which Lewis electron-dot structure is correct for carbon dioxide, $C_1{O}_2$, assuming all atoms have complete octets and formal charges are minimized?

• A. $O=C=O$ (each O has two lone pairs; C has no lone pairs)
• B. $O-C-O$ (each O has three lone pairs; C has no lone pairs)
• C. $O-C\equiv O$ (one O has three lone pairs; the other O has one lone pair)
• D. $O\equiv C\equiv O$ (each O has one lone pair; C has no lone pairs)

Answer: (A)
