I ran across something saying that n-butanamine is miscible in water while butanol is only partially soluble. Is this correct? Can anyone offer an explanation? I would have guessed that the decreased polarity of the amine relative to the alcohol would have resulted in lower solubility for n-butanamine.
Out of butanamine and butanol, butanol is more soluble in water due to higher electronegativity of oxygen . And as butanol have more polar oxygen so it will be more attracted towards water and form H bond.so it is soluble but amine are miscible due to enthalpies that will release out because of electron donating nature of nitrogen.
