A) \[Te{{F}_{2}}\]
B) \[lCl_{2}^{-}\]
C) \[SbC{{l}_{3}}\]
D) \[BaC{{l}_{2}}\]
Correct Answer: B
Solution :
| Ionic compounds are more soluble in water or in aqueous medium. |
| Ionic character \[\propto \] size of cation (if anion is same) The order of size of cation is |
| \[N{{a}^{+}}>Z{{n}^{2+}}>C{{u}^{2+}}\] |
| \[\therefore \]The order of ionic character and hence, of solubility in water is as\[N{{a}_{2}}S>ZnS>CuS\] |
