John Gibson (chemist)

from Wikipedia, the free encyclopedia

John Gibson (born May 13, 1855 in Edinburgh , † January 1, 1914 ) was a Scottish chemist .

Gibson attended the Edinburgh Academy and then studied chemistry in Heidelberg with Robert Bunsen , Hermann Kopp and Gustav Robert Kirchhoff . In 1876 he graduated with a doctorate in philosophy . On his return he became an assistant to Alexander Crum Brown at the University of Edinburgh . In 1881 he became chief assistant of the laboratory, where he taught for eleven years. In 1892 he became professor of chemistry at Heriot-Watt College . He was awarded the Challenger Medal . In 1877 he was elected a Fellow of the Royal Society of Edinburgh .

He did research on electrolysis and analyzed manganese nodules .

In 1892 Gibson published together with Crum Brown the so-called Crum-Brown-Gibson rule for the prediction and explanation of the orientation of the substituents on benzene and its derivatives .

The rule referred to the correlation that a meta-substitution takes place for a substituent X in which the hydrogen compound HX can be converted into HOX by direct oxidation .
