Vedclass · Answer

(D) $1$. In an aqueous medium,$Li^{+}$ has the maximum hydrated radius due to its high charge density,which leads to extensive hydration. Thus,the order $Li^{+}_{(aq)} > Na^{+}_{(aq)} > K^{+}_{(aq)} > Rb^{+}_{(aq)} > Cs^{+}_{(aq)}$ is correct.$2$. For halogens,the bond dissociation energy order is $Cl_2 > Br_2 > F_2 > I_2$. $F_2$ has a lower bond dissociation energy than $Cl_2$ due to significant lone pair-lone pair repulsion between the small fluorine atoms.$3$. For alkaline earth metal sulfates,the solubility decreases down the group because the hydration energy decreases more rapidly than the lattice energy. Thus,$BeSO_4 > MgSO_4 > CaSO_4$ is correct.Therefore,all the given statements are correct.
