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.
