Select the complexes that exhibit geometric isomerism. check all that apply. check all that apply. [co(h2o)2(ox)2]− [co(h2o)2(nh3)2(ox)]+ [co(en)3]3+ [ni(co)2cl2] [ni(nh3)2(en)2]2+

Geometric isomerism in another name is called cis-trans isomerism or it is called E-Z isomerism.
[Co(H2O)2(ox)2]- it is an octahedral complex which has two of bidentate ligand and another two of ligand. It exists as cis-trans isomers.
[Co(en)3]³+ it is an octahedral complex which has three bidentate ligands and it cannot exist as cis-trans isomers.
[Ni(CO)2CL2] is a square planar complex which has two of one ligand another two of ligand. It exists as cis-trans isomers.
[Co(H2O)2 (NH3)2(ox)]+ it is an octahedral complex with one of bidentate ligand two of each another ligand. It exists as cis-trans isomers.
[Ni(NH3)2 (en)2]²+ is an octahedral complex with one of a bidentate ligand and two each of another ligand. It exists as cis-trans isomers.
