Optional Molecular Shapes Project – Due Monday 5/14/12 You will create a presentation using the application of your choice (Animoto, Glogster, PhotoPeach, VoiceThread, WIX, Prezi). You will include the information presented below in your presentation. Finally, you will submit the link to your published product into the Google Form on my Website. Research Molecular Shapes (see list below). Use the concepts behind VSEPR Theory to briefly explain why/how each molecular shape occurs including: State the bond angle(s) according to the VSEPR Theory (2pts each shape). Provide an example substance for each shape (2pts each shape). Identify the number of shared electron pairs and lone electron pairs for each shape below (2pts each shape). Molecular Shapes: Linear Bent Trigonal Planar Trigonal Pyramidal Tetrahedral I. Create a Graphic of Linear (10pt) Bent (10pt) Trigonal Planar (10pt) Trigonal Pyramidal (10pt) Tetrahedral (10pt) (Some suggestions for creating your image: use a program like Paint, Sumo paint, etc… create a drawing and scan it in, or create models with household items and take a picture) Your graphic must be self created NO COPYING OF IMAGES FROM THE INTERNET OR BOOKS. Polar vs. Nonpolar. Research the difference between polar and nonpolar geometries. Identify which molecular shapes are polar and nonpolar. Define Polar (2pts) Define Nonpolar (2pts) Identify the polarity of each of the shapes above (2pts each shape) Helpful References Textbook Websites: http://www.tutor-pages.com/Chemistry/Molecular_Geometry/Polar_Or_Nonpolar.html http://intro.chem.okstate.edu/1314f00/lecture/chapter10/vsepr.html http://www.sparknotes.com/testprep/books/sat2/chemistry/chapter4section8.rhtml http://preparatorychemistry.com/Bishop_molecular_polarity.htm http://library.thinkquest.org/10429/low/geometry/geobody.htm http://misterguch.brinkster.net/VSEPR.html Molecular Shapes Project Rubric Points Possible Linear Bond Angles Example Substance Shared/Lone Pair of electrons Graphic Polarity Bent Bond Angles Example Substance Shared/Lone Pair of electrons Graphic Polarity Trigonal Planar Bond Angles Example Substance Shared/Lone Pair of electrons Graphic Polarity Trigonal Pyramidal Bond Angles Example Substance Shared/Lone Pair of electrons Graphic Polarity Tetrahedral Bond Angles Example Substance Shared/Lone Pair of electrons Graphic Polarity Polar Definition NonPolar Definition Spelling/Aesthetics Total 2 2 2 10 2 2 2 2 10 2 2 2 2 10 2 2 2 2 10 2 2 2 2 10 2 2 2 6 100 Points Earned
