Question

arrange the increasing order.
Aniline, ethanamine, 2-ethylethanamine (solubility in
water)​

Answer 1

Answer:

Ethylamine when added to water forms intermolecular H−bonds with water. And therefore it is most soluble in water.  

Diethyl amine having bigger alkyl chain forms weaker intermolecular hydrogen bonds.  

But aniline does not form H−bond with water to a very large extent due to the presence of a large hydrophobic −C

 group. Hence, aniline has least solubility in water.  

Hence the order of solubility is iii>ii>i
