### Which of the following complex ions has geometric isomers? Explain.a) \([Co(NH_3)_6]^{3+}\)b) \([Co(en)_3]^{3+}\)c) Tetrahedral-\([Co(ox)(NH_3)_2]^{2+}\)**Answer Explanation:**- **\([Co(NH_3)_6]^{3+}\)**: This complex ion does not exhibit geometric isomerism. The \(NH_3\) ligands are identical and symmetrically arranged around the central cobalt ion.- **\([Co(en)_3]^{3+}\)**: Ethylenediamine \((en)\) is a bidentate ligand. This complex ion does not exhibit geometric isomerism because the three bidentate ligands symmetrically arrange themselves around the cobalt ion.- **Tetrahedral-\([Co(ox)(NH_3)_2]^{2+}\)**: This complex ion can exhibit geometric isomerism. In a tetrahedral coordination, the oxalate (ox) ligand and the \(NH_3\) ligands can be arranged in different spatial configurations around the cobalt ion.### Accessing ToolbarFor the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).**Toolbar Options:**- **Bold (B)**- **Italic (I)**- **Underline (U)**- **Strikethrough (S)**- **Paragraph** (Dropdown to select paragraph formatting)- **Font Family** (e.g., Arial, Times New Roman)- **Font Size** (e.g., 14px)- **Alignment** (e.g., left, center, right, justify)**Note:** The toolbar provides essential formatting options such as bold, italics, underline, and paragraph alignment to help organize and highlight important points in your text.

Question

### Which of the following complex ions has geometric isomers? Explain.

a) \([Co(NH_3)_6]^{3+}\)

b) \([Co(en)_3]^{3+}\)

c) Tetrahedral-\([Co(ox)(NH_3)_2]^{2+}\)

**Answer Explanation:**

- **\([Co(NH_3)_6]^{3+}\)**: This complex ion does not exhibit geometric isomerism. The \(NH_3\) ligands are identical and symmetrically arranged around the central cobalt ion.

- **\([Co(en)_3]^{3+}\)**: Ethylenediamine \((en)\) is a bidentate ligand. This complex ion does not exhibit geometric isomerism because the three bidentate ligands symmetrically arrange themselves around the cobalt ion.

- **Tetrahedral-\([Co(ox)(NH_3)_2]^{2+}\)**: This complex ion can exhibit geometric isomerism. In a tetrahedral coordination, the oxalate (ox) ligand and the \(NH_3\) ligands can be arranged in different spatial configurations around the cobalt ion.
