It holds that the actual electronic structure of the molecule is a resonance hybrid of the different possible resonance structures.
But one of the more interesting features on the Nissan Resonance hybrid is the side-view cameras that eliminate the mirrors.
Had Kekule known in his time about quantum theory's concept of molecular orbitals introduced in the late 1920s, he would have melted his two structures into what is now called a "resonance hybrid." Molecular orbital theory, which accounts for chemical bonding by describing where electrons are likely to be found around a molecule, is presented in today's general chemistry courses as a modern refinement of Kekule's valence bond theory, which describes how electrons localized around atoms interact to form bonds.
