1.	Which of the following pairs represents linkage isomers?A. (a) `[Cu(NH_3)_4][PtCl_4]` and `[Pt(NH_3)_4][CuCl_4]`B. (b) `[Pd(PPh_3)_2(NCS)_2` and `[Pd(PPh_3)_2(SCN)_2]`C. (c) `[Co(NH_3)_5]NO_3SO_4` and `[Co(NH_3)_5SO_4]NO_3`D. (d) `[PtCl_2(NH_3)_4]Br` and `[PtBr_2(NH_3)_4Cl_2`
Answer» Correct Answer - B Linkage isomers are caused due to the presence of ambidentate ligands `[Pd(PPh_3)_2(NCS)_2` and `[Pd(PPH_3)_2(SCN)_2]` is a linkage isomers due to SCN, an ambidentate ligand. Thus, SCN can linked to Pd by both N as well as S through their lone pairs.
