$CuCl_2$

Vedclass · Answer

(C) $CuCl$ contains $Cu^+$ ion with $3d^{10}$ configuration. All electrons are paired,so it is colorless.$ScCl_3$ contains $Sc^{3+}$ ion with $3d^0$ configuration. It has no unpaired electrons,so it is colorless.$CuCl_2$ contains $Cu^{2+}$ ion with $3d^9$ configuration. It has one unpaired electron,which allows for $d-d$ transitions,making it colored.$TiCl_4$ contains $Ti^{4+}$ ion with $3d^0$ configuration. It has no unpaired electrons,so it is colorless.Therefore,$CuCl_2$ is the colored compound.

List-$I$	List-$II$
$(1)$ $Ti^+$	$(A)$ $(n-1)d^4ns^2$
$(2)$ $_{30}Zn$	$(B)$ $(n-1)d^{10}ns^1$
$(3)$ $_{24}Cr$	$(C)$ $(n-1)d^2ns^0$
$(4)$ $_{29}Cu$	$(D)$ $(n-1)d^5ns^1$
	$(E)$ $(n-1)d^0ns^2$
	$(F)$ $(n-1)d^{10}ns^2$
