could I get help with all parts of this mechanism please :)

Curved arrows are used to illustrate the flow of electrons. Using the provided starting and product structures, draw the curved electron-pushing arrows for the following reaction or mechanistic steps. Be sure to account for all bond-breaking and bond-making steps. :Br:1 Select to Add Arrows Select to Add Arrows Curved arrows are used to illustrate the flow of electrons.
