cannot be predicted

Vedclass · Answer

(D) $CdI_2$ exhibits a pink colour due to the high polarizability of the large $I^{-}$ ion by the $Cd^{2+}$ cation,which possesses a pseudo-noble gas configuration $(d^{10})$.In $CdCl_2$,the $Cl^{-}$ ion is much smaller and less polarizable than the $I^{-}$ ion.Therefore,the extent of polarization by $Cd^{2+}$ is significantly less in $CdCl_2$,and it does not exhibit the same colour as $CdI_2$.Thus,the colour of $CdCl_2$ cannot be predicted based on the colour of $CdI_2$.

If $CdI_2$ is pink in colour,the $CdCl_2$ will be ........... coloured.
