Question

In which of the following complexes does the transition metal have a de configuration? Select one: O a. Cu(H20)62- O b. PtCl42- O c. Ni(CO) O d. Fe(CN) O e. Zn(NH3)42-

thanks in advance

Answer 1

1 I a) cu CH₂0) 72t Here en is ind configuration and strucking of the complex is octahednal. b) Ptele 72 hene pt is in de configuration and structun of the complex is square planar os pt(II) has greater efse square planan geometry as it is of 4th period. 30 45 4 720 Pt: 1LALA DE in prene depe Value and Structine c) Niccoly Hene Nilis in d to configuration of the complex is Tetrahednal. 32 4 4P Ni: 02/12 14(1419 O in Nilcoy 503 and CN 73- Here fe is in d (Los) Configunation structure is octahedral. 32 4 4P Fe T T N Next N. in Fe(CN) - d2sp3 ON 72ť es in (NH); Here en is in a configunation, and structune of the complex is Tetrahednal, Zn in Zn(NH3)2+ 12111 L Zn-NH₂ Tp3 NH Therefore the answer of the given question is b) Ptch?

2 Linkage Isomerism: In this type of in enim? In this tappe of isomenism, ligands are attached to central atom via different donor atom. This tyr of isomerism is observed in presence of ambidentate ligands. Now in the given options only [Ni(H₂O), (SCN) J Soy has ambidentate ligand within the co-ordnation sphene Therefore only option of i.e [Ni(H2O), (SCN)] sou will show linkage isomers - 2 Ha Ha Otto OH 1042 and Ho Ni - Nes/sou Ho-Ni-SEN/Sou THE OH2 I Y co-ondination sphene Linkage homens. 6 [NiC NHz) y Ch]el + doesnt have any ambidentate ligand this it will not show linkage isomenism. c) and d) id [Ni(NH3), cly] NO₂ and [Ni(H₂O) el ] B CN have ambidentate ligands (1.2 No, and SCN nexpectively) but thoose are not inside the co-ordination sphene therefore can't show linkage isomeriam e) Ni CH lychle doesnt have any ambidentate ligand they it will not show linkage isomerism. mbidentate ligands: These are monddentate ligands that ssible places, like. NOL, SEN, ROOD EN No places.like. se can bind have in two possible for sureation 2 in Therefore the am connect answer A [Ni(H₂O), ESCN) J Soy.

3. of and - ol and b) il MAGB and MA6, these toppe of complexes doesn't show geometrical isomerism. e M A₂ B₂ C₂ These type of complex will show geometrical pomenism and also optical isomerism. like- O 2 No-fae, men ixoners.
