Organic chemical reaction network
WitrynaChemistry moves from in-person lab and the classroom to the computer, as working in a virtual chemistry laboratory and viewing simulations provide additional ways of learning chemistry. This page is a collection of all the simulations created by the American Association of Chemistry Teachers. Several new simulations are added each year. WitrynaOn the most abstract level, the millions of known chemicals and reactions constituting organic chemistry can be represented as a complex network 6, in which compounds …
