The bonding in a molecule of carbon dioxide can be represented by a dot-and-cross diagram. Which diagram is correct?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
ADot-and-cross diagram showing a central carbon atom forming two double covalent bonds with two oxygen atoms, where each oxygen atom has two lone pairs of electrons.
BDot-and-cross diagram showing a central carbon atom forming a single covalent bond with one oxygen atom and a triple covalent bond with another oxygen atom.
CDot-and-cross diagram showing a central carbon atom forming two double covalent bonds with two oxygen atoms, where each oxygen atom has one lone pair of electrons.
DDot-and-cross diagram showing a central carbon atom forming two single covalent bonds with two oxygen atoms, where each oxygen atom has three lone pairs of electrons.
✓ Correct answer
A: Dot-and-cross diagram showing a central carbon atom forming two double covalent bonds with two oxygen atoms, where each oxygen atom has two lone pairs of electrons.
