Both CO2 and SiO2 appear to have valid Lewis structures. Using the molecular orbital model, why then are CO2 molecules stable and SiO2 molecules not stable?


▸ CO2 is able to form sigma bonds and SiO2 is not.

▸ The silicon 3p valence orbitals do not overlap very effectively with the smaller oxygen 2p orbitals.

▸ The carbon atom is larger than the silicon atom, giving carbon a higher electron density and thus better pi bonding.

▸ Silicon prefers to bond to other silicon atoms over oxygen atoms.

▸ At least two of these are correct.
