JEE MAIN - Chemistry (2022 - 26th June Morning Shift - No. 5)
Choose the correct stability order of group 13 elements in their + 1 oxidation state :
Al < Ga < In < Tl
Tl < In < Ga < Al
Al < Ga < Tl < In
Al < Tl < Ga < In
Explanation
Due to inert pair effect, stability of +3 oxidation state
decreases and that of +1 oxidation state increases
for (down the group) group 13 elements.
So, the correct order of stability of group 13 elements in their +1 oxidation state is Al < Ga < In < Tl.
So, the correct order of stability of group 13 elements in their +1 oxidation state is Al < Ga < In < Tl.
