Vedclass · Answer

(C) According to Fajan's rule,the polarising power of a cation is directly proportional to its charge and inversely proportional to its size. In option $C$,the order of polarising power is $Na^{+} Comparing $Na^{+}$ and $K^{+}$,$Na^{+}$ is smaller than $K^{+}$,so $Na^{+}$ has higher polarising power than $K^{+}$. Therefore,the correct order should be $K^{+} Thus,the order given in option $C$ is incorrect.
