Recall that a carbon atom behaves as if it possesses four valence electrons. Given this information, what is the MOST likely structural formula for carbon dioxide (CO₂)?

Question

Quizplus · Accepted Answer

The structural formula for carbon dioxide is typically represented as O=C=O, meaning that there is a double bond between each oxygen atom and the central carbon atom. This arrangement satisfies the valency of each atom involved. Options A, C, and D all have extra bonds that are not accounted for in the valence shell of the carbon atom.
