How chemical reactions happen

Chemical reactions are processes of transforming one substance to another through changing chemical bonds. The study of chemical reactions is at the core of chemistry. This activity is a series of virtual experiments for studying how chemical reactions happen. We will focus on organic chemical reactions and will not address issues related to biochemical reactions that are mostly mediated by the aqueous environment. Throughout this activity, when we say bonds, we only mean covalent bonds.
