$LiCl$

Vedclass · Answer

(A) Lithium is the smallest in size among the alkali metals. Due to its small size,the $Li^{+}$ ion has a high charge density and can polarize water molecules more effectively than other alkali metal ions. This high polarizing power allows $LiCl$ to crystallize as a hydrate (specifically $LiCl \cdot 2H_2O$). As the size of the alkali metal ions increases down the group,their polarizing power decreases,which is why other alkali metal chlorides typically form anhydrous salts.

Which among the following alkali metal chlorides crystallises in the form of a hydrate?
