Ingen av dei foreslåtte strukturformlane kunne nemleg forklara bindingane i stoffet. Dette fordi <a href="/wiki/Karbon" title="Karbon">karbon</a> vanlegvis dannar fire bindingar og <a href="/wiki/Hydrogen" title="Hydrogen">hydrogen</a> berre ei. </p><p>Løysinga ligg i å sjå på bindingane som elektronbanar, <a href="/wiki/Orbital" title="Orbital">orbitalar</a>. Det følgjande diagrammet syner plasseringa av desse orbitalane: </p><p><span class="mw-default-size" typeof="mw:File"><a href="/wiki/Fil:Benzen-orbitaler.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/2/2a/Benzen-orbitaler.jpg" decoding="async" width="278" height="153" class="mw-file-element" data-file-width="278" data-file-height="153" /></a></span> </p><p>Sidan orbitalane ligg utanfor planet til atoma, kan dei påverka kvarandre fritt. Dermed vert dei forskuve. Det gjer at alle seks karbonatoma deler på elektrona i staden for at dei er bundne til eitt karbonatom. Det er ikkje nok elektron til å danna dobbeltbindingar mellom alle karbonatoma, men dei «ekstra» elektrona styrkar alle bindingane i ringen like mykje. <a href="/w/index.php?title=Molekylorbitalen&action=edit&redlink=1" class="new" title="Molekylorbitalen (sida finst ikkje)">Molekylorbitalen</a> som vert danna har π-symmetri. </p><p>Denne forma for forskyving av elektron vert kalla <a href="/w/index.php?title=Aromatisk&action=edit&redlink=1" class="new" title="Aromatisk (sida finst ikkje)">aromatisk</a>, og den gir benzen stor stabilitet.
