Which compound has a Lewis structure that contains at least one double bond?

One common compound with a Lewis structure that contains at least one double bond is carbon dioxide (CO₂). In its Lewis structure, the carbon atom is double-bonded to each of the two oxygen atoms, resulting in a linear geometry. This double bond is represented by two pairs of shared electrons between the carbon and each oxygen atom. Other examples include ethylene (C₂H₄) and formaldehyde (CH₂O).
