Name:

Molecular Structure and Geometry

 

Instructions:
In this exercise you will assign geometry, molecular structure, and hybridization to five substances using the Valence Shell Electron Pair Repulsiion (VSEPR) theory. The five substances have been randomly selected from a database. (In order for the substances to be randomly selected your browser must have Javascript enabled.) You should print out this sheet with your browser and fill in the following chart using the answer codes in the Geometry and Structure Answer Code chart.

Notes:
Inspiration for this assignment came from an article by David N. Cash in the December 2000 issue of Chem13 News,. Currently the database of substances includes 4 of Linear geometry, 8 of Trigonal Planar geometry, 18 of Tetrahedral geometry, 14 of Trigonal Bypyramidal geometry, and 12 of Octahedral geometry. This allows for the creation of 96,768 different worksheets.
