WebOct 24, 2024 · The curly arrows drawn in blue show the movement of electrons in the reaction. They start with the lone pair of electrons on the nitrogen and flow in one direction to give a new bond and a new lone … 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…
