    Which is maximum hydrated?

    A)  \[NaCl\]                             

    B)  \[MgC{{l}_{2}}\]  

    C)  \[AlC{{l}_{3}}\]                                

    D)  \[SiC{{l}_{4}}\]

    Correct Answer: D

    Solution :

                    Smaller cation has, larger charge thus will show, larger hydration. Size of cation\[N{{a}^{+}}>M{{g}^{2+}}>A{{l}^{3+}}>S{{i}^{4+}}\to \] minimum size charge\[\xrightarrow[{}]{{}}\]maximum charge Thus,\[SiC{{l}_{4}}\]is maximum hydrated.
