Molecular Geometry

Flashcards covering key concepts of molecular geometry based on electron group arrangements and associated bond angles.

Electron Group Arrangement

The spatial arrangement of electron groups around a central atom.

Linear Geometry

A molecular geometry with 2 electron groups and bond angles of 180°.

Trigonal Planar Geometry

A molecular shape with 3 electron groups, resulting in bond angles of 120°.

Bent Geometry (3 Electron Groups)

Occurs when there are 3 electron groups and 1 lone pair, with bond angles less than 120°.

Tetrahedral Geometry

A molecular shape with 4 electron groups and approximate bond angles of 109.5°.

Trigonal Pyramid Geometry

A molecular shape with 3 bonding groups and 1 lone pair, with bond angles typically around 107°.

Trigonal Bipyramidal Geometry

A molecular geometry with 5 electron groups, featuring bond angles of 90° and 120°.

See-Saw Geometry

Occurs in a trigonal bipyramidal arrangement with 1 lone pair, resulting in bond angles less than 90° and 120°.

Square Pyramidal Geometry

A molecular shape with 6 electron groups and 1 lone pair, with bond angles around 90° and less than 90°.

Square Planar Geometry

A molecular geometry with 6 electron groups and 2 lone pairs, with bond angles of 90°.
