University of Colorado, Boulder - CHEM 101Lab 5 Molecular Modeling report

Document Content and Description Below

Data Insert photos or scans of each drawn Lewis structure and sketch as described in the lab procedure, include photos of built models, and answer any additional questions. Activity 1 • Expla... in why the balls representing fluorine and hydrogen have only one peg, while oxygen has two and carbon has four. Both Fluorine and Hydrogen can only bond with one electron, because Fluorine has 7 valence electrons it can only increase to 8 for stability, and Hydrogen only has one valence electron and one bonding domain meaning it can bond but only to one molecule. Meanwhile, because Oxygen has 6 valence electrons it can only take up two more to satisfy the octet rule, and Carbon has four because Carbon has 4 valence electrons meaning it has 4 open domains for a bonding to occur. To add to this, in terms of pegs, Oxygen can make double bonds, and Carbon in incredibly rare cases can make quadruple bonds, while Fluorine and Hydrogen will only make single bonds [Show More]
