Each double bond in carbon dioxide (CO₂) represents two pairs of shared electrons.

In CO₂, the structure involves two double bonds between the carbon and each oxygen atom, where each double bond consists of one sigma bond and one pi bond, leading to the sharing of two pairs of electrons between the carbon and each oxygen.
