$BaSO_4 > SrSO_4 > CaSO_4 > MgSO_4 > BeSO_4$ (Solubility)

Vedclass · Answer

(D) $1$. $BeO$ is amphoteric,while $MgO$ is basic. Thus,$BeO $2$. In a group,acidic strength of oxides decreases as metallic character increases. Thus,$SO_2 > SeO_2 > TeO_2$ is correct.$3$. Melting point of alkali metal halides decreases as the size of the cation increases due to decrease in lattice energy. Thus,$NaCl > KCl > RbCl > CsCl$ is correct.$4$. For alkaline earth metal sulfates,solubility decreases down the group due to the decrease in hydration energy being more significant than the decrease in lattice energy. The correct order is $BeSO_4 > MgSO_4 > CaSO_4 > SrSO_4 > BaSO_4$. Therefore,the given order is incorrect.

List-$I$	List-$II$
$A$. $Al^{3+} < Mg^{2+} < Na^{+} < F^{-}$	$I$. Ionisation Enthalpy
$B$. $B < C < O < N$	$II$. Metallic character
$C$. $B < Al < Mg < K$	$III$. Electronegativity
$D$. $Si < P < S < Cl$	$IV$. Ionic radii
