WebWhat are curly arrows? They are a shorthand for rationalising what happens during a reaction. Mostly used in organic chemistry, they illustrate which bonds are broken and formed, or how charges are distributed around molecules through resonance. Arrow pushing or electron pushing is a technique used to describe the progression of organic chemistry reaction mechanisms. 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. The arrows illustrate the movement of electrons as bonds between atoms are broken and formed.
