Study Notes
Molecular Geometry Types
- Linear: Characterized by 2 bonding pairs and 0 nonbonding pairs, resulting in a straight-line arrangement.
- Trigonal Planar: Defined by 3 bonding pairs and 0 nonbonding pairs, leading to a flat, triangular structure.
Molecular Shapes with Nonbonding Pairs
- Bent (1): Formed with 2 bonding pairs and 1 nonbonding pair, creating an angular shape due to repulsion from the lone pair.
- Tetrahedral: Consists of 4 bonding pairs and 0 nonbonding pairs, producing a three-dimensional shape with bond angles of approximately 109.5°.
Complex Molecular Structures
- Trigonal Pyramidal: Involves 3 bonding pairs and 1 nonbonding pair, resulting in a pyramid-like shape due to the presence of the lone pair.
- Bent (2): Comprises 2 bonding pairs and 2 nonbonding pairs, leading to a more pronounced angle than the first bent configuration.
Higher Coordination Geometries
- Trigonal Bipyramidal: Features 5 bonding pairs and 0 nonbonding pairs, displaying two distinct types of bond angles (90° and 120°).
- Octahedral: Contains 6 bonding pairs and 0 nonbonding pairs, forming a symmetrical shape with 90° bond angles between adjacent bonds.
