Arrange the following in increasing order of their basic strength:
$C_{2} H_{5} N H_{2}, C_{6} H_{5} N H_{2}, N H_{3}, C_{6} H_{5} C H_{2} N H_{2}$ and $(C_{2} H_{5})_{2} N H$

Solution

Basic strength:- Basic strength of an amine is determined by availability of electron from nitrogen.
Basic strength increasing order:-
$(C_{2} H_{5})_{2} N H > C_{2} H_{5} N H_{2} > N H_{3} > C_{6} H_{5} C H_{2} N H_{2} > C_{6} H_{5} N H_{2}$
