Vedclass · Answer

(A) In the $13^{th}$ group,as we move down the group,the stability of the $+1$ oxidation state increases due to the inert pair effect,while the stability of the $+3$ oxidation state decreases.For $+3$ ions,the stability order is $Al^{3+} > Ga^{3+} > In^{3+} > Tl^{3+}$. Thus,$Ga^{3+} For $+1$ ions,the stability order is $Ga^{+} For $Tl$,the $+1$ state is more stable than the $+3$ state $(Tl^{+} > Tl^{3+})$.For $Ga$,the $+3$ state is more stable than the $+1$ state $(Ga^{3+} > Ga^{+})$.Therefore,the incorrect statement is $Ga^{3+} < In^{3+} < Tl^{3+}$.
