    Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. [1] It was first developed by Sir Robert Robinson.In using arrow pushing, "curved arrows" or "curly arrows" are drawn on the structural formulae of reactants in a chemical equation to show the reaction mechanism.

    Organic chemistry has a strong tradition of naming a specific reaction to its inventor or inventors and a long list of so-called named reactions exists, conservatively estimated at 1000. A very old named reaction is the Claisen rearrangement (1912) and a recent named reaction is the Bingel reaction (1993).

    Organic chemistry is the study of organic, or carbon based, molecules.Carbon is the only element that can make bonds with itself so that chains are produced, silicon has similar properties, but Carbon is a main element in everyday life, and thus, is lucky enough to have a whole subject in chemistry dedicated to it.
