Vedclass · Answer

(B) $I$. $LiF$ is less soluble in water than $NaF$ due to its very high lattice energy. This statement is correct.$II$. $LiCl$ and $MgCl_2$ are covalent in nature and are soluble in ethanol, not insoluble. This statement is incorrect.$III$. Both $Li$ and $Mg$ show diagonal relationship and both form nitrides ($Li_3N$ and $Mg_3N_2$) on reaction with $N_2$. This statement is correct.$IV$. $Na_2CO_3$ is thermally stable and does not decompose to give $CO_2$ on heating. This statement is incorrect.Therefore, statements $I$ and $III$ are correct.
