- SHAPES OF MOLECULES
- Linear
- 2 bonding pairs, 0 lone pairs
- 180°
- e.g CO2, CS2, HCN, BeF2
- 2 BP (of e-) repel equally
- Trigonal Planar
- 3 bonding pairs, 0 lone pairs
- 120°
- 3 BP repel equally
- e.g BF3, AlCl3, SO3, NO3-, CO3 2-
- Tetrahedral
- 4 bonding pairs, 0 lone pairs
- 109.5°
- 4 BP repel equally
- e.g SiCl4, SO4 2-, ClO4-, NH4+
- Pyramidal
- 3 bonding pairs, 1 lone pair
- 107°
- e.g. NCl3, PF3, ClO3, H3O+
- 3 BP, 1 LP- LP repel more than BP
- Octahedral
- 6 BP, 0 LP
- 6 BP repel equally
- 90°
- e.g SF6
- Bent/ Non-Linear
- 104.5°
- 2 bonding pairs, 2 lone pairs
- e.g. OCl2, H2O, OF2
- 2 BP, 2 LP -- LP repel more than BP (by 5°)
- Linear
