Title: Why does carbon monoxide have a much lower melting point than sodium oxide? Post by: Datchile on Nov 7, 2012 Carbon Monoxide is covalent.
Sodium Oxide is ionic. I don't know if that matters, but please help me out.. I think that has something to do with it. Title: Why does carbon monoxide have a much lower melting point than sodium oxide? Post by: smshanic on Nov 7, 2012 Carbon Monoxide is covalent.
Sodium Oxide is ionic. does matter. Molecules with covalent bonds have much lower melting point than those with ionic bonds. I dunno why tho haha. Sorry. Title: Why does carbon monoxide have a much lower melting point than sodium oxide? Post by: dbynum1 on Nov 7, 2012 Also because ionic molecules have much stronger intermolecular forces, and the higher the intermolecular forces, the higher the melting point. So carbon monoxide would have to have a lower melting point.
