Question

Mention the basicity of hydrides of the following elements – F, C, O, N.​

Answer 1

Answer:

In group 15, the hydrides of the formula XH

3

have a lone pair on the central atom. As we go down the group, size of the atom increases. And hence, electron density over the group 15 element decreases. Thus the tendency to donate electrons decreases, hence basicity decreases down the group as

NH

3

>PH

3

>AsH

3

>SbH
