Note: there is more than one answer and you must choose all of the molecules in the list that exhibit resonance.) Atoms or ions with the same electronic configurations are said to be isoelectronic to each other or to have the same isoelectronicity. Which of these molecules or ions exhibit resonance? (CO3)2- 4. Here is the example of Benzene. Then, give its molecular geometry (if it has a structure we have not studied, write "none") Formulas for molecules and ions are correct Answer: I don't have the ability to post these structures right now.....so, check the book or make your best guess. The formal charge of an atom in a molecule is the hypotheticalcharge the atom would have if we could redistribute the electrons in the bonds evenly between the atoms. This is much more common than one might expect as most covalent bonds have some ionic character and so are less than a full covalent bond (bond order < 1.0). How many of the following exhibit resonance? An aldehyde is oxidized b. This theory states that molecules for which two or more satisfactory Lewis structures can be drawn are an average, or hybrid, of these structures. The resonance hybrid of this polyatomic ion, obtained from its different resonance structures, can be used to explain the equal bond lengths, as illustrated below.The resonance hybrid of NO2– suggests that each oxygen atom holds a partial charge of magnitude -½. This structure satisfies the octet rule for each atom and has 26e−.
