2. Show the reaction of 4-aminophenol with KOH. Indicate which layer (aqueous or organic) each component in the reaction will mainly reside in.

----> The reaction of 4-aminophenol with potassium hydroxide (KOH) is an example of a typical nucleophilic substitution reaction. When 4-aminophenol is treated with KOH, the amine group in 4-aminophenol reacts with the hydroxide ion in KOH to form a salt, 4-aminophenol, and water.

The reaction can be written as follows:

4-Aminophenol + Potassium hydroxide 4-Aminophenolate + Water

RNH2 + KOH RNH3+ + K+ + H2O

In this reaction, both 4-aminophenol and KOH are soluble in water, so the reaction takes place in the aqueous layer. The resulting product, 4-aminophenol, is also soluble in water and will mainly reside in the aqueous layer. The water produced in the reaction will also mainly reside in the aqueous layer.

4. To the salt obtained in question 2, what reagent would you add to recover 4-aminophenol in its nonpolar form? Show the reaction. What would happen if you added too much of this reagent? Show the reaction.

Please answer question 4.
