Quizplus · Accepted Answer

Cyclohexanamine is a basic compound, so it will form a salt with the acidic aqueous HCl layer, making it water-soluble and allowing for extraction into the aqueous layer (Layer B). 2-octanol and potassium chloride will remain in the organic layer (Layer A). Therefore, cyclohexanamine can be extracted from Layer B.
