CHEM 101 Spring 2020 Lab 7: Molecular Models and Chemical Bonds Name Date Objectives: -To draw electron dot formulas and structural formulas of specific molecules -To explore using online model building kits Procedure: For each of the following molecules, please do the following: 1) Draw its electron dot formula and verify that it is correct by adding up all valence electrons involved (both bonding and nonbonding) & listing the total. 2) Draw its structural formula, which is essentially the electron dot formula with the bonding "electron dots" replaced by the lines for single/double/triple bonds. 3) Using http://molview.org/ and/or http://biomodel.uah.es/en/DIY/JSME/draw.en.htm to help you, draw the structural formula on the website to see what the "ball and stick" molecular model looks like. Draw this 3-D model to the best of your ability, putting the chemical symbols for each atom in their respective balls. a. Before you draw the 3-Dimensional model yourself, you should probably look up (via the Internet) a picture of what the structural formula should look like to verify you have the correct answer.
