8.3 Self Check Quiz
Lewis Dot Structure Practice
Today you will be practicing drawing Lewis dot structures and beginning to explore two new concepts. Use the two helpful links below to
Resonance and Expanded Octets (Hooray for exceptions!)
Your assignment for the day: On a separate sheet of paper before the end of the hour, complete the Lewis dot structures for the following molecules and answer the following questions.
FOR 1-4 INCLUDE THE NUMBER OF TOTAL VALENCE ELECTRONS IN THE MOLECULE.
1. CH2Cl2
2. CO
3. CO2
4. the nitrate ion
5. Give an example of a Lewis structure with an incomplete octet.
6. Give an example of a Lewis structure with an expanded octet.
7. Draw all three resonance structures for the nitrate ion. describe how each resonance structure is different from the other using complete sentences.
Useful website #1: Go to this website and begin practicing. NOTE: When using this website, pay attention to the links to the left of the text AND when you notice empty white space, click on it. It will help.
