【答案】：碱性NH3＞N2H4＞NH2OHN2H4和NH2OH可以看成NH3中的一个H被—NH2和—OH取代而得到的产物，由于电负性H＜N＜O，吸引电子能力H＜N＜O，因而NH3被取代后给电子能力减弱：NH3＞N2H4＞NH2OH，则碱性：NH3＞N2H4＞NH2OH。
氨气（NH3）和羟胺（NH2OH）都具有碱性，但它们的碱性强度有所不同。氨气（NH3）本身并不是碱，但在水溶液中与水结合成氨水时才表现出碱性。这是因为氨水的弱电解作用使其与水中的H+结合，导致溶液中H+的浓度相对OH-浓度降低，从而表现出碱性。羟胺（NH2OH）的水溶液同样呈弱碱性，其原理与氨气的...

看起来是超理，不过，话说我对N.H.O三个元素组成的化合物特别感兴趣：NH3＞NH2OH＞N2H2（碱性比联氨还弱，极易分解）＞PH3＞AsH3 其中，磷化氢和砷化氢几乎没有碱性，都可以与特别强的强酸成盐：如PH4I，但遇水分解
