उत्तर

The correct decreasing order of basic strength of the following species is \[\ce{NH^{-}2 > OH- > NH3 > H2O}\].

Explanation:

Due to higher electronegativity of O than N atom, \[\ce{O – H}\] bond is more polar than \[\ce{N – H}\] bond. Hence, \[\ce{O – H}\] is more acidic in nature than \[\ce{N – H}\] bond. Now, \[\ce{NH2}\] and \[\ce{OH}\] have negative charge due to which they are more basic than \[\ce{NH3}\] and \[\ce{H2O}\].
