Answer 1

We'll try to draw cis and trans isomers and will also check if they are optically active or not.For that we'll see the plane if symmetry in a complex. For Fac and Mer isomers there should be three ligands of each type in a octahedral geometry.

Solution - Isomers of [Fe Ccody cl]* Here, there are six ligands attached, so it will have . octahedral arrangment. • Cis isomer (v) • Trans i somer (V) cogant-na [Same gps Fel fel on Same Side] - con tacco [Same gooups on opposite Sicher] cou... " • No optical isomers (X) . As in cis and trans isomers, we can see will be va plane of symmetry present, Hence optically inactive plane De er plane (Trans ) (cis) • No fac / mer isomers (X) so fac mer isomers exist in Compound type [mA,B3 ] cagi (co ery(NH3)3] HUN NH NH3 C facial (fac) Isomer Meridonal (mer) Isomer

Hence in (Fe(Cosy Cl_]+2 there is no fee mer Isomers. Answers . cis Isomer • Trans Isomer coccini pt', cocco Post-B (Pt (en)Cla] . No Fac , mer i somers because compound cloesn't have IMA,B3] type: ,cen len→ Bidentate ligand NH - CH-CH_NH2] [Ethyleme cliammine] . Complex would not have cis and trans isomers because all the possible spatial arrangement of the ligands round the metal is same. Jo No optical isomers un given Complex, Because the o complex being square - planar, is planas and o has plane of symmetry. Hence optically inactive to 1 e tee plane [ Answer :- None of above]
