About the Department

The Department of Chemistry of Cotton College was among the first Departments of the College that started in the year 1901, and the Chemistry Building is the oldest building from where this institute started its epic journey. Recently, with a fund received from the UGC, the historic building has been preserved as a heritage building and is being used to teach undergraduate and postgraduate students. Prof. Chunilal De was the first teacher of the Department, who taught both Chemistry and Physics. The Department has been functioning from the original century-old building of Cotton College. In 2001, a new building, the Harish Chandra Goswami Bhawan, was constructed alongside the old building. This Department of erstwhile Cotton College was able to receive an...
