Question

Canvas Classes · Accepted Answer

Linear shape requires sp hybridization with no net angular distortion.

Step 1 — Analyse each species:

| Species | Central atom | Bonds | Lone pairs | Shape |
|---------|-------------|-------|-----------|-------|
|  | Xe | 2 | 3 | Linear ✓ |
|  | I | 2 | 2 | Bent ✗ |
|  | C (middle) | 2 double bonds | 0 | Linear ✓ |
|  | I | 2 | 3 | Linear ✓ |
|  | C | 2 double bonds | 0 | Linear ✓ |
|  | S | 2 | 1 | Bent ✗ |
|  | Be | 2 | 0 | Linear ✓ |
|  | B | 2 | 1 | Bent ✗ |

Step 2:  → 5 linear species
