Permanganate ion is not isostructural with

Options

A. managanate ion
B. Cromate ion
C. Chlorate ion
D. Perchlorate ion

Answer

To solve the question "Permanganate ion is not isostructural with," we need to analyze the structures of various ions mentioned in the video transcript.

### Step-by-Step Solution:

1. **Identify the Structure of Permanganate Ion (MnO4⁻):**
- The permanganate ion (MnO4⁻) has a tetrahedral structure. This is due to the arrangement of four oxygen atoms around the manganese atom, with one of the oxygen atoms having a negative charge.

2. **Identify the Structure of Manganate Ion (MnO4²⁻):**
- The manganate ion (MnO4²⁻) also has a tetrahedral structure. It consists of manganese bonded to four oxygen atoms, similar to the permanganate ion.

3. **Identify the Structure of Chromate Ion (CrO4²⁻):**
- The chromate ion (CrO4²⁻) has a tetrahedral structure as well. It consists of chromium bonded to four oxygen atoms, which is analogous to both permanganate and manganate.

4. **Identify the Structure of Chlorate Ion (ClO3⁻):**
- The chlorate ion (ClO3⁻) has a trigonal pyramidal structure. It consists of a chlorine atom bonded to three oxygen atoms, with one of the oxygen atoms having a double bond and two lone pairs on the chlorine atom.

5. **Identify the Structure of Perchlorate Ion (ClO4⁻):**
- The perchlorate ion (ClO4⁻) has a tetrahedral structure. It consists of a chlorine atom bonded to four oxygen atoms, similar to the permanganate ion.

6. **Conclusion:**
- Among the ions discussed, the permanganate ion (MnO4⁻) is not isostructural with the chlorate ion (ClO3⁻) because the chlorate ion has a trigonal pyramidal structure, while the permanganate ion has a tetrahedral structure.

### Final Answer:
Permanganate ion is not isostructural with **chlorate ion (ClO3⁻)**.
