Curved arrows are used to illustrate the flow of electrons. Follow the arrows and draw the first intermediate formed in this reaction and the final product. Include all lone-pairs. Ignore any inorganic byproducts. Curved arrows are used to illustrate the flow of electrons. Usir the provided starting and product structures, draw the curve, electron-pushing arrows for the following reaction or mechanistic steps. Be sure to account for all bond-breaking Curved arrows are used to illustrate the flow of electrons. Usina t Curved arrows are used to illustrate the flow of electrons.
