Imagine you preformed Sn2 reaction to form N-methyl benzyl ammonium bromide. The only impurity present in N-methyl benzyl ammonium bromide after the reaction is the benzyl bromide starting material. Draw a flow chart to explain the steps needed to purify the neutral N-methyl benzyl amine by extraction?
