Vedclass · Answer

(D) The general electronic configuration of group $12$ elements $(Zn, Cd, Hg, Cn)$ is $(n-1)d^{10}ns^2$.Copper $(Cu)$ belongs to group $11$ and has an electronic configuration of $3d^{10}4s^1$.Zinc $(Zn)$ belongs to group $12$ and has an electronic configuration of $3d^{10}4s^2$.In option $D$,$Cu$ does not have the $(n-1)d^{10}ns^2$ configuration,while $Zn$ does.Therefore,the pair where both elements do not have this configuration is $Cu, Zn$.
