Vedclass · Answer

(B) The colour of transition metal complexes is generally due to $d-d$ transitions,which require the presence of unpaired $d$-electrons. In $Na_2CdCl_4$,the cadmium ion is $Cd^{2+}$. The electronic configuration of $Cd$ $(Z=48)$ is $[Kr] 4d^{10} 5s^2$. Thus,$Cd^{2+}$ has the configuration $[Kr] 4d^{10}$. Since the $d$-subshell is completely filled,there are no unpaired electrons available for $d-d$ transitions,making the compound colourless. Therefore,the correct option is $(B)$.
