Vedclass · Answer

(A) $1$. Conductivity in molten state depends on the mobility of ions. As the size of the cation increases,the ionic mobility increases,leading to higher conductivity. Thus,the order $Mg^{+2} $2$. Hydration energy is inversely proportional to the size of the ion. The correct order for hydration energy is $Li^{+1} > Na^{+1} > K^{+1} > Rb^{+1} > Cs^{+1}$. Therefore,the order given in option $B$ is incorrect.$3$. Reactivity of alkali metals increases down the group due to the ease of losing an electron. Thus,the order $Li $4$. Since option $B$ is incorrect,the correct answer is not 'All of them'.$5$. Re-evaluating the options: Option $A$ is correct (conductivity increases with size). Option $C$ is correct (reactivity increases down the group). Given the structure,the question likely intended to ask for the correct statement among the choices.
