Draw curved arrows for each step of the following mechanisms.
Note: you will have to explicitly redraw out the molecules yourself
to show bonds to hydrogens on heteroatoms that are breaking.
Remember to draw in all lone pairs that are being used as electron
sources for curved arrows – curved arrows must always come from
lone pairs or bonds!
