which type of bond and how many bonds would occur as carbon dioxide (CO2) is formed from carbon in group IVA and oxygen in group VIA

Question

A: two ionic bonds
B: one covalent bond
C: four covalent bonds
D: three metallic bonds

Answer 1

Carbon dioxide (CO₂) is formed from one carbon atom and two oxygen atoms. In this molecule, carbon forms covalent bonds with oxygen.

Specifically, each carbon-oxygen bond is a double bond, where two pairs of electrons are shared between the carbon and each oxygen atom. Thus, carbon forms two double bonds with two oxygen atoms, amounting to a total of four covalent bonds (two double bonds).

So the correct answer is:

C: four covalent bonds.
