प्रश्न
Account for the following.
Ethylamine is soluble in water whereas aniline is not.
उत्तर
Ethylamine when added to water forms intermolecular H-bonds with water and therefore it is soluble in water. But aniline does not form an H-bond with water to a very large extent due to the presence of a large hydrophobic –C6H5 group. Hence, aniline is insoluble in water.
