WebSep 2, 2024 · Curved arrows show movement of electrons. Therefore, any curved arrow mechanism starts from a lone pair of electrons or a covalent bond. Do not start them … 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. It is important to note that arrow pushi…
