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.
