Vedclass · Answer

(A) $LiF$ has a very high lattice enthalpy due to its small size,which makes it less soluble in water. Thus,statement $(i)$ is correct.The polarizing power of $Na^{+}$ is higher than that of $Cs^{+}$ due to its smaller ionic radius. Consequently,$NaCl$ has more covalent character and is less ionic than $CsCl$. Thus,statement $(ii)$ is correct.The formation of alkali metal halides from their constituent elements is a highly exothermic process,as it involves the release of energy to form a stable crystal lattice. Thus,statement $(iii)$ is incorrect.
