Question

(D) $1$. $BeCl_2$ is covalent,while $LiCl$ is ionic. Ionic compounds have higher electrical conductivity in molten state,so $BeCl_2 < LiCl$ is correct

Vedclass · Accepted Answer

$LiF > LiCl > LiBr > LiI$ (Solubility order in water)

Vedclass · Answer

(D) $1$. $BeCl_2$ is covalent,while $LiCl$ is ionic. Ionic compounds have higher electrical conductivity in molten state,so $BeCl_2 $2$. Thermal stability of ionic compounds increases with the lattice energy and the charge density of the cation. $NaF $3$. For sulfates of alkaline earth metals,the thermal stability increases down the group as the size of the cation increases,making the lattice more stable. Thus,$BeSO_4 $4$. Solubility of lithium halides in water depends on the hydration energy vs lattice energy. $LiF$ is the least soluble due to very high lattice energy,while $LiI$ is the most soluble. The correct order is $LiF < LiCl < LiBr < LiI$. Therefore,option $D$ is the incorrect order.

Choose the incorrect order of the given properties.
