Post 100

This post number 100!!! (so what?)

Time to look back 100 years. What is the best article in JACS of 100 years ago (june 1907)?





This is so nice. A brass strip with white corks as hydrogen atoms, black corks as carbon atoms, and springs.

In order to obtain a the ring structure the model is bent round to form a circle.
Beautiful! More than 40 years after Kekulé's paper!



You could make more proposed structure (like the ones from Ladenburg, Dewar, Adolf Claus, Armstrong and Baeyer) with meccano as a hobby. The Claus/Armstrong-Baeyer benzene model is easily constructed the paper says, but the most important message is the endline.




I haven't received it yet...

Interesting. After this paper was published, Prof. Lang became a commanding officer at the University of Toronto during WWI.

Here's a link to his portrait.

"Colonel W. R. Lang VD was the first Commanding Officer of the University of Toronto Contingent COTC. He commanded it during and after the First World War (1914-1925) and later became the first Director of Military Studies at this University. He was appointed to The Canadian General Staff in 1914 and among other responsibilities was in charge of Coast Defence in the Maritimes in 1918. Before the war he was a professor of Chemistry at this University. He was president of the Canadian Operatic Society."
