Which one of the following complex is not expected to exhibit isomerism?A. `[Ni(NH_(3))_(4)(H_(2)O_(2)]^(2+)`B. `[Pt(NH_(3))_(2)CI_(2)]`C. `[Ni(NH_(3))_(2)CI_(2)]`D. `[Ni(en)_(3)]^(2+)` |

Answer» Correct Answer - A `[Ni(NH_(3))_(2)C1_(2)` is a tetrahedral complex. Tetrahedral complexes do not show geometrical isomerism because the relative positions of the unidentate ligands bonded to the central metal are the same with respect to each other. `[Ni(NH_(3))_(2)C1_(2)]` is a square planar complex. It exhibits geometrical isomerism. In cis isomer two `H_(2)O` ligands are at `90^(@)` while in trans isomer two `H_(2)O` ligands are at `180^(@)` angle. `[Pt(NH_(3))_(2)C1_(2)]` is a square planar complex. It also exhibits geometrical isomerism as two `NH_(3)` (or two C1) could be at `90^(@)` or at 180: `[Ni(en)_(3)]^(3+)` , an octachedral complex exhibits optical isomerism |
