Which is least basic ? SbH_(3),PH_(3), NH_(3),AsH_(3) ? |
| Answer» Solution :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. | |
