Aromatic rings

Since I was at primary school I have known of the story of Jörmungandr, the giant snake which was in the sea. The story was that the snake went right around the world and caused the tides to move. When I was at school I read a story about how the gods chained up the monster wolf (Fenrir), in the story it mentioned in passing the giant snake. Another giant snake (Ouroboros) was drawn by Lucas Jennis (1590-1630) and is shown below.

A snake (Ouroboros) eating his tail

You might ask why I mention the story of the giant snake, I will now explain why I am showing you the tail eating snake. The reason is that the shape of the snake is rather like the pi system of an aromatic ring. I have to explain to you that a recurring theme in organic chemistry is aromacitiy. An aromatic molecule has special stability which is important. I will tell you more soon.
