Vedclass · Answer

(D) According to $Fajan's$ rule,the covalent character in an ionic compound increases as the size of the anion increases. For the given halides of $Cu^{2+}$,the size of the halide ions follows the order: $F^- $CuF_2$ is primarily ionic due to the small size and high electronegativity of the $F^-$ ion. $CuCl_2$ and $CuBr_2$ exhibit significant covalent character due to the larger size and higher polarizability of $Cl^-$ and $Br^-$ ions. Therefore,both $(a)$ and $(b)$ are correct statements.

Amongst $CuF_2$,$CuCl_2$ and $CuBr_2$,which of the following statements is correct regarding their nature?
