To insure you keep up with the material in this fast paced unit,you should expect a routine Daily 5 - five questions about the previous day's materialTest Discussion Question Topics1. Intermolecular Forces vs. Bonding 2. What is a molecule and what is NOT a molecule. 3. Polar vs. NonPolar Bonding Extra Credit Information for 3rd Quarter - Spring Semester |

Websites To read and study from - intermolecular forces |
http://www.elmhurst.edu/~chm/vchembook/index.html - use this index to read and study the ionic, covalent and intermolecular force presentations. A great resource - clear and to the point. |

Nomenclature
Please see your Nomenclature Flow Chart for help in naming. You will have several practice pages, also. Your text discusses this on pages 248-251 Some web sites that may help... |
http://science.widener.edu/~svanbram/chem145/ch03/index.html - a good summary http://www.fairbornchempage.com/Resources/Prefixes.htm - did you forget the prefixes? http://chemsite.lsrhs.net/ChemicalBonds/naming_molecular.html - general rules summary http://science.widener.edu/svb/tutorial/namingcsn7.html - practice naming with instant answers for ionic and molecular |
Dot DiagramsYou have several handouts that discuss this, pages 243 -247 in your text cover this and some helpful web sites may include: |
Basic Concept Questions - answer these questions and place into your notes1. What is the fundamental unit of a molecular compound? 2. What is the fundamental unit of an ionic compound? 3. What elements form molecular compounds (or have covalent bonds?) 4. What type of compounds have low boiling points? high boiling points? 5. Is water a good conductor? 6. Examples of molecular compounds 7. Which type of compound usually dissolves in water and conduct electricity when dissolved? 8. What is a covalent bond? 9. Why do atoms form bonds? 10. What is a polar bond? 11. How is a polar covalent bond different from a non polar covalent bond? 12. What is electronegativity? 13. If the electronegativity difference is very large and the material contains a metal, what type of bond will form? 14. If the electronegativity difference is small or zero between two nonmetals in a bond, what type of covalent bond will be formed? 15. The more electronegative atom in a molecular compound will develop what partial charge?
