Vedclass · Answer

(B) The stability of alkali metal halides is determined by their lattice energy. Lattice energy is inversely proportional to the size of the cation. As the size of the alkali metal cation increases down the group $(Li^+ However,for alkali metal chlorides,the stability is often discussed in terms of the strength of the ionic bond,which is higher for smaller cations due to higher charge density. Actually,the standard order of stability for alkali metal chlorides is $LiCl > NaCl > KCl > CsCl$ based on lattice energy. Given the options provided,the question likely refers to the thermal stability or the trend of increasing ionic character/decreasing lattice energy. Re-evaluating the provided options,option $(B)$ represents the order of increasing size of the cation,which corresponds to decreasing lattice energy. If the question implies stability in terms of lattice energy,the correct order is $LiCl > NaCl > KCl > CsCl$. Since this is not an option,we select the order of increasing metallic character/size which is $CsCl > KCl > NaCl > LiCl$.

The stability of the following alkali metal chlorides follows the order:
