🧠 hybridisation needs exactly 4 electron groups (bonds + lone pairs) on the central atom. Count for each species.
| Species | Bonds | Lone pairs on central | Total | Hybridisation | |---|---|---|---|---| | | 3 (resonance) | 0 | 3 | sp² | | | 3 | 0 | 3 | sp² | | | 2 | 2 | 4 | sp³ ✓ | | | 3 | 1 | 4 | sp³ ✓ |
⚡ For : Cl has 7 valence e. 2 bonds use 2e from Cl; remaining 5e → 2 LP + 1 radical? No: with −1 charge, Cl has 8e available → 2 bonds (4e) + 2 LP (4e) = sp³.
