Question

The correct shape and I–I–I bond angles respectively in  ion are:

Canvas Classes · Accepted Answer

Step 1 — VSEPR analysis of :
- Central I: 2 bonds + 3 lone pairs = 5 electron pairs
- 5 electron pairs → trigonal bipyramidal electron geometry
- 3 lone pairs occupy equatorial positions
- 2 bonds in axial positions

Step 2 — Molecular shape:
With 2 axial bonds and 3 equatorial lone pairs, the molecular shape is linear (bond angle = 180°).

Step 3 — Bond angle:
The I–I–I angle = 180° (linear)

Answer: Option (4) — Linear; 180°
