Lidocaine isolation. The final product is removed from the organic layer by extraction with hydrochloric acid solution. Draw the curved arrows for the proton transfer reaction that takes place, and draw the resulting product. Explain how this reaction enables the removal of the lidocaine from the organic layer.
