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 $Ga^{3+} < In^{3+} < Tl^{3+}$.

Column-$I$	Column-$II$
$A$. Diborane	$1$. Used as a flux for soldering metals
$B$. Gallium	$2$. Crystalline form of silica
$C$. Borax	$3$. Banana bonds
$D$. Alumino silicate	$4$. Low melting,high boiling,useful for measuring high temperatures
$E$. Quartz	$5$. Used as catalyst in petrochemical industries
