Dear Student,
Ethanol and 1-propanol can be distinguished with the help of iodoform test. As ethanol gives yellow precipitates of iodoform by reacting with iodine in presence of base. But 1-Propanol does not undergo this reaction.
Ethanol and 2-propanol cannot be distinguished with the help of iodoform test. Because both give iodoform reaction. So distinction between both can be done with the help of Lucas test. When ethanol is treated with Lucas reagent (equimolar mixture of conc. HCl and anhydrous ZnCl2), no turbidity is formed.
But turbidity appears in about five minutes, when 2-propanol is treated with Lucas reagent.
