Blog - The Carbon Muse

A model of the double and single covalent bonds of carbon within a benzene ring, the subject of today’s blog post.

(note: this is the historical model of Kekulé)

Cool. Springs used to depict covalent bonds. They vibrate ! They rotate ! They have numerous degrees of freedom !

It's fortunate that it's only a massive model of a (carcinogenic) benzene molecule you have on your desk, and not the real thing. Organic stuff can be... messy ;-)

Graphite or Diamond, a question of bonds.

my fiancee had to use these suckers for a whole semester of Orgo. It was not fun - one of the hardest classes @ Cornell.

Steve thansk for submitting your photos in our group... if you have something scietifically challenging you can post it as a puzzle in a new thread...

Cool. Found via the Google platform photo on Wikipedia's article of such.

Hm... if that's supposed to be a benzene molecule model, it is incorrect. The carbon-carbon bonds in benzene and other aromatic compounds are not alternating single- and double bonds but aromatic bonds (all C-C bonds are equal):
en.wikipedia.org/wiki/Benzene#Structure

It's a good photo, anyhow :)

Of course the model is inaccurate as Patsy in Monty Python and the Holy Grail said: "It's only a model." Any model not matter how good, is going to be inaccurate in some way. The point is whether it is accurate enough for your needs.

Ah yes, and then there are the needs of art and story telling.

Here's the context: The photo was the illustration for a blog post called Ode to Carbon, which opens:

"I took a close look at the benzene molecular model on my desk, and visions of nested snake loops danced in my head… Is there something unique about the carbon in carbon-based life forms?"

So, I m rendering the original mental model of Kekulé in 1865 (as seen in the diagram at the top of your wikipedia link). Here is an artsy version of the story of Kekulé's waking dream of the snake chasing its tail...

Also, from the art perspective, I needed the double bonds of the toy model for a good visual... =)

Delocalized bonds are tough to render with sticks and springs... but they have a wonderful aroma ;-)

I was being too clever and too heady. Should have known :)

I think that the benzene molecule is cute.
