Study Notes
Molecular and Electron Geometries
-
Linear Molecular Geometry
- Comprises 2 electron groups and 2 bonding groups.
- Characterized by the absence of lone pairs.
-
Trigonal Planar Molecular Geometry
- Consists of 3 electron groups and 3 bonding groups.
- No lone pairs contribute to its flat, triangular shape.
-
Bent Molecular Geometry (from Trigonal Planar)
- Features 3 electron groups with 2 bonding groups and 1 lone pair.
- The presence of the lone pair creates a bent structure rather than a straight line.
-
Tetrahedral Molecular Geometry
- Contains 4 electron groups and 4 bonding groups.
- Exhibits a three-dimensional shape with no lone pairs.
-
Trigonal Pyramidal Molecular Geometry
- Composed of 4 electron groups, 3 bonding groups, and 1 lone pair.
- The lone pair distorts the geometry from a perfect tetrahedron to a pyramid shape.
-
Bent Molecular Geometry (from Tetrahedral)
- Involves 4 electron groups, 2 bonding groups, and 2 lone pairs.
- Enhanced lone pair repulsion leads to a more pronounced bent structure.
-
Trigonal Bipyramidal Molecular Geometry
- Has 5 electron groups with all 5 as bonding groups.
- Displays equatorial and axial positions with no lone pairs affecting the form.
-
Seesaw Molecular Geometry
- Encompasses 5 electron groups, 4 bonding groups, and 1 lone pair.
- The presence of a lone pair creates a seesaw shape.
-
T-Shaped Molecular Geometry
- Involves 5 electron groups, 3 bonding groups, and 2 lone pairs.
- The arrangement of lone pairs leads to a T-shaped structure.
-
Linear Molecular Geometry (from Trigonal Bipyramidal)
- Features 5 electron groups, with 2 bonding groups and 3 lone pairs.
- The positioning of lone pairs results in a linear arrangement.
-
Octahedral Molecular Geometry
- Consists of 6 electron groups fully engaged in bonding (6 bonding groups).
- Exhibits a symmetric three-dimensional octahedral shape without lone pairs.
-
Square Pyramidal Molecular Geometry
- Comprises 6 electron groups, with 5 bonding groups and 1 lone pair.
- The lone pair causes distortion, creating a square pyramid instead of a flat plane.
-
Square Planar Molecular Geometry
- Consists of 6 electron groups, with 4 bonding groups and 2 lone pairs.
- The presence of 2 lone pairs opposite each other leads to a flat square arrangement.
