CHEM 1320 Lecture Notes - Lecture 31: Trigonal Planar Molecular Geometry, Trigonal Bipyramidal Molecular Geometry, Lattice Energy
Document Summary
1. the force of attraction between oppositely charged particles is directly proportional to the product of the charges. Electron group geometry: overview, ve basic arrangements of electron groups around a central atom, maximum of six bonding electron groups (1) very rare to have more than 6. 2. these arrangement s results in ve different basic electron geometries. 3. resonance: it doesn"t matter which resonance form you use since the electron geometry will be the same. B. linear electron geometry: two electron groups: groups occupy positions on opposite sides of the central atom. C. trigonal planar electron geometry: three electron groups: groups occupy positions in the shape of a triangle around the central atom. 2. trigonal planar geometry: bond angle: 120, derivatives, no lone pairs: trigonal shape, one lone pair: bent shape. D. tetrahedral electron geometry: four electron groups: groups occupy positions in the shape of a tetrahedron around the central atom.
