Carbon dioxide, or "CO"_2, has three resonance structures, out of which one is a major contributor. Get Answer. [S-]C(N)=O Resonance structures do not "resonate" or flip back and forth as the name implies. Notice again, that only the arrangement of electrons is different in resonance structures – atoms have the same connectivity. Theory of resonance, in chemistry, theory by which the actual normal state of a molecule is represented not by a single valence-bond structure but by a combination of several alternative distinct structures. The oxygens share the negative charge with each other, stabilizing it, and reducing the charge on either atom. And that is the definition of identical … Briefly, if you follow the octet rule, you will see the oxygen atoms are connected linearly, where the central oxygen atom is always positively charged, and the terminal oxygen atoms are either negatively charged with a single bond or neutral with a double bond. Resonance Structures Practice Question 5 The more resonance forms a … I. RESONANCE STRUCTURES. Complete the given structure by adding nonbonding electrons and formal charges.
