The shape/structure of  and , respectively are:

Canvas Classes · Accepted Answer

Step 1 — Analyse :
- Xe has 5 F bonds + 2 lone pairs (charge −1 adds 1 electron)
- Total electron pairs = 7 → pentagonal bipyramidal electron geometry
- 2 lone pairs occupy axial positions → pentagonal planar shape

Step 2 — Analyse :
- Xe has 3 O bonds + 2 F bonds + 0 lone pairs = 5 electron pairs
- 5 electron pairs → trigonal bipyramidal electron geometry
- No lone pairs → shape is trigonal bipyramidal

Step 3 — Match:  = pentagonal planar;  = trigonal bipyramidal

Answer: Option (1)
