Answer:
CO2
Explanations:
What is a molecular covalent bond?
Molecular covalent bond are bond which involves the sharing of electrons between elements. This type of bond usually occur among two non-metals.
In a carbon dioxide molecule, a carbon atom is joined by four covalent bonds to two oxygen atoms, which have two covalent bonds each. In CO2, one atom of carbon is covalently bonded with two atoms of oxygen.
Based on this explanation, we can conclude that the only molecular covalent bond is CO2
