Kekule Structures

[Maya Johnson 2a]

Hi, can someone explain Kekule structures please?

Generally, Kekule structures are very similar to Lewis structures, in that they show lines for chemical bonds, but differ in that they do not show lone pairs. More specifically, you may be talking about Kekule's famous structure for benzene, where he shows alternating single and double bonds between the six carbons in the benzene ring. Many organic structures with aromatic rings will be shown in this way, with alternating single and double bonds, even though we now know that this is generally an incorrect way of thinking about resonance. The more correct way is to think of the electrons as being equally shared, somewhere between a single and a double bond.

I'm pretty sure Kekule structures are Lewis structures. They show an inaccurate representation because they suggest both carbon-carbon double bonds and carbon-carbon single bonds (aka two different types of carbon-carbon bonds in benzene).

this sounds very unfamiliar to me, was it mentioned in lecture previously? if so, can someone tell me which one please?
