Label:
-nucleophile
-electrophile
-leaving group
Draw a reasonable, step by step arrow pushing mechanism for
the overall reaction. You may abbreviate non-involved parts of any
of the molecules with 'R' groups, and you can assume that water is
present in the reaction (to act as either an acid or a base).
