    The question is a little confusing to me. I suppose Fe, IF, Kr, and IF5 are covalent compounds and would be classified as molecules. ScBr3 probably is more ionic and not classified as molecules but as ions. H2S is primarily covalent; as a gas it surely must be covalent and molecular but as a solution it does ionize slightly.
