Why + 3 oxidation state is stable in heavier element of group 15? |
|
Answer» Solution : (1) All theelementsof group15show oxdiationstateof `+3`and `+5` (2) Down the group, the stability of +5 oxidation state decreases while that of+3 state increases DUE to inert pair effect of `ns^(2)` electrons. (3) Large amount of ENERGY is NEEDED to REMOVE all five electrons (`ns^(2), np^(3)`) from the valence shell, hence stable +5 oxidation state cannot be formed by heavier element like Bi of group 15 having large atomic size. |
