Detailed Solution

Primary amines with three (or) more carbon atoms are liquids and still higher ones are solids. The lower amines forms hydrogen bonding with water because of less hydrophobic character but as the molecular mass of amines can increase, then hydrophobic character also increases-which ultimately decreases the hydrogen bonding with water.
