Q5 (15 pts) Identify the electrophiles and nucleophiles that participate in the following reactions (just indicate them on the structures). Also name the type of the reaction (which could be ambiguous sometimes, but try your best). For a redox reaction, indicate the oxidant and the reductant as well.
