Ethylamine is soluble in water whereas aniline is not . Give reason.

Explanation

Ethylamine when added to water forms intermolecular H - bonds with water . And therefore it is soluble in water . But anilne does not from H-bond with water to a very large extent due to the presence of a large hydrophobic `- C_6 H_5` group Hence, anilne is insoluble in water .
