Among the three elements, hydrogen has the least electronegativity value, carbon comes second and oxygen has the highest value. In general, molecules with multiple resonance structures will be more stable than one with . The atom shares three of its four valence electrons with Hydrogen atoms and rests one electron with the hydroxyl group. To understand why this is the case, we must dive deeper into the factors affecting chemical polarity, keeping acetone in mind. In the above figure, all of the constituent atoms have filled outermost shells. The Lewis structure was named after Gilbert N.
