प्रश्न
Arrange the following in the increasing order of property mentioned :
NH3, PH3, AsH3, SbH3, BiH3 (Base strength)
उत्तर
(b) Base strength: BiH3 < SbH3 < PH3 < NH3
On moving down the group, the size of the central atom increases. This decreases the electron density on the central atom and thereby affecting the electron-donating ability of the atom. Hence, the basic strength decreases on moving down the group.
