B. Bent `XeF_(2)` and pyramidal `XeO_(3)`
C. Bent `XeF_(2)` and planer `XeO_(3)`
D. Linear `XeF_(2)` and pyramide `XeO_(3)`

Answer

To determine the xenon compounds that are isostructural with \( IBr_2^- \) and \( BrO_3^- \), we need to analyze the structures of these compounds and find the corresponding xenon compounds.

### Step 1: Analyze the structure of \( IBr_2^- \)

1. **Determine the number of valence electrons**:
- Iodine (I) has 7 valence electrons.
- Each Bromine (Br) has 7 valence electrons, and there are 2 of them.
- The negative charge adds 1 electron.
- Total = \( 7 + 2(7) + 1 = 22 \) valence electrons.

2. **Draw the Lewis structure**:
- Iodine is the central atom, bonded to two bromine atoms.
- There are 3 lone pairs on the iodine atom.
- The structure is linear due to the arrangement of the bonds and lone pairs.

### Step 2: Identify the isostructural xenon compound

- The xenon compound that has a similar structure (linear) is \( XeBr_2 \).
- In \( XeBr_2 \), xenon is the central atom, bonded to two bromine atoms, with 3 lone pairs, resulting in a linear structure.

### Step 3: Analyze the structure of \( BrO_3^- \)

1. **Determine the number of valence electrons**:
- Each Bromine (Br) has 7 valence electrons.
- Each Oxygen (O) has 6 valence electrons, and there are 3 of them.
- The negative charge adds 1 electron.
- Total = \( 7 + 3(6) + 1 = 28 \) valence electrons.

2. **Draw the Lewis structure**:
- Bromine is the central atom, bonded to three oxygen atoms.
- There is 1 lone pair on the bromine atom.
- The structure is trigonal pyramidal due to the arrangement of the bonds and lone pairs.

### Step 4: Identify the isostructural xenon compound

- The xenon compound that has a similar structure (trigonal pyramidal) is \( XeO_3 \).
- In \( XeO_3 \), xenon is the central atom, bonded to three oxygen atoms, with 1 lone pair, resulting in a trigonal pyramidal structure.

### Conclusion

The xenon compounds that are isostructural with \( IBr_2^- \) and \( BrO_3^- \) are:
- \( XeBr_2 \) (isostructural with \( IBr_2^- \))
- \( XeO_3 \) (isostructural with \( BrO_3^- \))

### Final Answer:
The xenon compounds that are isostructural with \( IBr_2^- \) and \( BrO_3^- \) respectively are \( XeBr_2 \) and \( XeO_3 \).
