Question:
Which of the following pairs of compounds is isoelectronic and isostructural?
Which of the following pairs of compounds is isoelectronic and isostructural?
Show Hint
Linear species like \( IBr_2^- \) and \( XeF_2 \) follow the VSEPR theory, having three lone pairs and two bonding pairs on the central atom.

- \( TeI_2, XeF_2 \)
- \( IBr_2^-, XeF_2 \)
- \( IF_5, XeF_5 \)
- \( BeCl_2, XeF_2 \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding isoelectronic and isostructural concepts.
- Isoelectronic species have the same total number of electrons.
- Isostructural species have the same shape and hybridization.
Step 2: Analyzing the given pairs.
- \( IBr_2^- \) and \( XeF_2 \) both have 22 valence electrons.
- Both species have a linear structure due to sp\(^3\)d hybridization with three lone pairs.
