Question

What is the increasing order of basic property of hydrides of group 15 elements?

Answer 1

Answer:

Explanation:

Due to the presence of lone pairs of electron,the hydrides of these elements are basic (Lewis bases) in nature.The basicity decreases with the size of the central atom due to diffusion of electrons over large volume i.e down the group,as the size of the elements increases the electron density on element decreases

therefore, the order will be:

NH3 > PH3 > AsH3 > SbH3 > BiH3
