1.	Arrange the following compounds in the decreasing order of their solubility in water :(a) Ethyl amine, diethyl amine and triethyl amine.(b) Ethyl amine, n-propyl amine and n-butyl amine.(c) n-Butane, n -butyl alcohol and n-butyl amine.
Answer» (a) Ethyl amine, diethyl amine and triethyl amine : Diethyl amine > triethyl amine > ethyl amine (The reason that ethyl group has greater +1 effect than methyl group) (b) Ethyl amine, n-propyl amine and n-butyl amine : n-butyl amine < n-propyl amine < ethyl amine (c) n-Butane, n -butyl alcohol and n-butyl amine : n-butyl alcohol < n-butyl amine < n-butane

Arrange the following compounds in the decreasing order of their solubility in water :(a) Ethyl amine, diethyl amine and triethyl amine.(b) Ethyl amine, n-propyl amine and n-butyl amine.(c) n-Butane, n -butyl alcohol and n-butyl amine.

Answer»

(a) Ethyl amine, diethyl amine and triethyl amine :

Diethyl amine > triethyl amine > ethyl amine

(The reason that ethyl group has greater +1 effect than methyl group)

(b) Ethyl amine, n-propyl amine and n-butyl amine :

n-butyl amine < n-propyl amine < ethyl amine

(c) n-Butane, n -butyl alcohol and n-butyl amine :

n-butyl alcohol < n-butyl amine < n-butane
