Arrange the following in an incrasing order of absic strength in water :
`C_(6)H_(5)NH_(2),(C_(2)H_(5))NH,(C_(2)H_(5))N and NH_(3)`
(ii) Arrange the following in increasing order of baisc strength is gas phase:

Explanation

(i)The incrasing order of basic stength in water of the given amines and ammonia follows the following order
`C_(6)H_(5)NH_(2)ltNH_(3)lt(C_(2)H_(5))_(3)Nlt(C_(2)H_(5))_(2)NH`
(ii)The inceasing order of bsic stength in gas phase of the given of the given amines followes the order
`CH_(3)NHltC_(2)H_(5)NH_(2)lt(C_(2)H_(5))ltNHlt(C_(2)H_(5))_(3)N`
