Korner, Wilhelm

The technique of isomer counting used by Werner to prove the configuration of cobalt-ammines and other complexes did not originate with him, but had been used earlier by Wilhelm Korner for benzene derivatives in 1874, and was also suggested by Jacobus Henricus van t Hoff in 1875. However, the technique of comparing the number and type of isomers actually prepared with the number and type theoretically predicted for different configurations probably attained its zenith with Werner. Not only did he use this method to discredit completely the chain theory but also to... 

This work was actually carried out by Wilhelm K rner, of the University of Milan, and was the first example of the Korner method of absolute orientation.)... 

The German chemist Wilhelm Korner (1839-1925) observed in 1874 that each of the three dibromobenzenes A, B, and C furnished a different number of tribromobenzenes upon further bromination, aUowing himto assign their respective structures. Try to do the same on the basis of the following results.
