    <div class="sphx-glr-thumbcontainer" tooltip="August Kekulé (1865) proposed that benzene&#x27;s six carbons form a ring with alternating single and double bonds, and soon after that the two alternating arrangements interconvert, which explained why benzene has only one ortho-disubstituted isomer. A Kekulé structure is a choice of double bonds that gives every carbon exactly one; in graph language, a perfect matching of the carbon skeleton.">
