Vedclass · Answer

(D) According to Fajan's rule,covalent character increases with an increase in the charge on the cation and a decrease in the size of the cation.For the given compounds,the charges on the cations are: $Si^{4+}$,$Al^{3+}$,$Mg^{2+}$,and $Ca^{2+}$.As the positive charge on the cation increases,its polarizing power increases,leading to greater covalent character.The order of charge is $Si^{4+} > Al^{3+} > Mg^{2+} > Ca^{2+}$.Therefore,the correct order of covalent nature is $SiCl_4 > AlCl_3 > MgCl_2 > CaCl_2$.
