Study Notes
Molecular Geometries and Electron Geometries
- Trigonal Bipyramidal: Characterized by five pairs of electrons. Seen in IF4+, SF4, PCl5, and I3− as electron geometry.
- Square Pyramidal: Present in BrF5, resulting from four bonds and one lone pair.
- Octahedral: Six bonds connected to a central atom. Identified in SF6 and ICl5 as both electron and molecular geometry.
- Linear Geometry: Two bonding pairs of electrons with bond angle of 180°. Observed in HCN, CO2, and BeH2.
- T-Shaped Geometry: Found in ClF3, resulting from three bonding pairs and two lone pairs.
- Trigonal Pyramidal: Observed in PCl3 and NF3, obtained from three bonding pairs and one lone pair.
- Bent Shape: Found in SH2 and H2O, occurring due to two bonding pairs and two lone pairs.
- Square Pyramid: Characterizes ICl5 with five bonds; one bond to a central atom forms a pyramid shape.
- Trigonal Planar Geometry: Three bonding pairs with 120° angles. Identified in SO3, CH2O, and BH3.
- Tetrahedral Geometry: Four bonding pairs in a 109.5° configuration. Seen in H2O and CCl4; essential in bonding scenarios.
- Seesaw Shape: Depicted by SF4, generated from four bonding pairs and one lone pair on a central atom.
- Key Bond Angles: Understanding bond angles helps predict molecular geometry—linear (180°), trigonal planar (120°), tetrahedral (109.5°), and octahedral (90° or 180°).
