Study Notes
Electron Geometry and Molecular Geometry
- PCl5 has both Electron Geometry and Molecular Geometry classified as Trigonal Bipyramidal.
- SF4 has Electron Geometry of Trigonal Bipyramidal, while its Molecular Geometry is a See-saw shape.
- In a trigonal bipyramidal arrangement, lone pair electrons are located equatorially to minimize repulsion.
- ClF3 has Electron Geometry of Trigonal Bipyramidal and Molecular Geometry of T-Shape.
- I3- demonstrates Trigonal Bipyramidal Electron Geometry and Linear Molecular Geometry.
- BrF5 features Electron Geometry of Octahedral and a Molecular Geometry described as Square Pyramidal.
- XeF4 also exhibits Octahedral Electron Geometry while having a Square Planar Molecular Geometry.
Isomerism
- Structural (constitutional) isomers share the same chemical formula but differ in atom connectivity.
- Stereoisomers have the same chemical formula and same atomic connectivity, but differ in spatial configuration.
- Enantiomers are stereoisomers that are non-superimposable mirror images.
- Diastereomers are stereoisomers that are non-superimposable but not mirror images.
Stereoisomers and Chiral Centers
- The number of stereoisomers for a molecule with chiral centers is calculated using the formula 2^n, where n represents the number of chiral centers, yielding 4 possible stereoisomers for two chiral centers.
- Non-superimposable mirror images cannot be aligned perfectly with their original counterparts, while superimposable images can match exactly.
Types of Isomers
- Enantiomers fall into the category of stereoisomers.
- Double bonded compounds cannot exhibit conformational isomers due to the absence of rotation about a double bond, but they can participate in geometric isomerism.
