Which is least basic ? `SbH_(3), PH_(3), NH_(3), AsH_(3)` ?

Text Solution

Verified by Experts

A compound which is most acidic is obviously least basic. Since `SbH_(3)` is most acidic, therefore, is it least basic.or As the size of the atom increases, electron density on the central atom decrease and hence basicity decreases. Thus `SbH_(3)` is least basic.
