Vedclass · Accepted Answer

$Lithium$ and $Magnesium$ show some similarities in their physical properties as they are diagonally placed in the periodic table.

Vedclass · Answer

(C) $LiCl$ is deliquescent and crystallises from aqueous solution as a hydrate,$LiCl \cdot 2H_{2}O$. The hydration enthalpies of alkaline earth metal ions decrease with an increase in ionic size down the group. The correct order of hydration enthalpy is $Be^{2+} > Mg^{2+} > Ca^{2+} > Sr^{2+} > Ba^{2+}$. $Lithium$ shows a diagonal relationship with $Magnesium$,hence their physical and chemical properties are similar. $Lithium$ is the hardest among all alkali metals.
