In aqueous solutions, the basic strength of amines decreases in the order

Answer»

`CH_(3)NH_(2) GT (CH_(3))_(2)NH_(2) gt (CH_(3))_(3)N`
`(CH_(3))_(2)NHgt(CH_(3))_(3)Ngt CH_(3)NH_(2)`
`(CH_(3))_(3)Ngt(CH_(3))_(2)NHgt CH_(3)NH_(2)`
`(CH_(3))_(2)NH gtCH_(3)NH_(2)gt(CH_(3))_(3)N`

Solution :Basic strength of mcthylamines DECREASES in the order:
`2^(@) gt 1^(@) gt 3^(@) i.e., (CH_(3))_(2)NH gt CH_(3)NH_(2)gt (CH_(3))_(3)N`
