Institute Of Theoretical Chemistry
The Division of Chemical Education of the American Chemical Society and NSF recognized in 1989 the need to foster the development of alternative General Chemistry Curriculum.
The main difficulty in teaching chemistry lies in the explanation of chemical phenomena on the basis of quantum chemistry when the teachers have to explain things that they hardly understand themselves.
In 2004 we placed on our web-site, ITChem.com, the draft of the General Chemistry textbook. In this text we explained the basic chemical bonds, chemical reactions and catalysis without using the quantum-chemical approach. In this context we explain the physical nature of the periodic law, Lewis’ rules, and the resonance rules etc.
