Question
Which of the following describes the current view of the two Kekulé structures for benzene?
A) they are both correct structures for benzene
Solution
The current view of the two Kekulé structures for benzene is that they are not two distinct structures, but rather two resonance forms of the same structure. This means that benzene does not alternate between these two structures, but rather exists as a hybrid of them. This view is based on experimental evidence that all the carbon-carbon bonds in benzene are of the same length, which is intermediate between the length of a single bond and a double bond. This is consistent with the idea that the electrons in the double bonds are delocalized over the entire ring, creating a system of resonance that gives benzene its characteristic stability. So, the answer is not exactly A) they are both correct structures for benzene, but rather they both contribute to the correct resonance hybrid structure of benzene.
