Solution

Ethylamine is soluble in water, whereas aniline is insoluble. This is because:
(1)Ethylamine is capable of forming hydrogen bonds with water as it is soluble but aniline the bulk carbon prevents the formation of effective hydrogen bonding and is not soluble. Ethylamine ( $C_{2} H_{5} {NH}_{2}$ )in addition to water forms intermolecular H−bonds with water. It is soluble in the water.
(2)Aniline( $C_{6} H_{5} {NH}_{2}$ ) does not undergo H−bonding with water to a very considerable extent due to the existence of a large hydrophobic $- C_{6} H_{5}$ group. Hence, aniline is insoluble in water.
