If you replaced P (phosphorus) with N (nitrogen) in the above compound, can the compound exist and why? (Hint: subenergy levels)?<br> <br> <br> <br> 3. Write the symbol for a polar bond, _____________ and write down how you have memorized the direction of the symbol <br> <br> ______________________________________________________________________________<br> <br> <br> <br> 4. What are the cut-offs of <nowiki>deltaEN</nowiki> for ionic bonds ______________,<br> <br> polar bond ______________, non-polar bond _____________<br> <br> <br> 5. What is the phrase Mr. <nowiki>McLeod</nowiki> makes you memorize to help remember the type of molecular polarity of a compound/polyatomic ion?<br> <br> <br> <br> <br> 6. List the species (e.g. ionic, metallic, polar, etc) from highest IMF to lowest IMF<br> ____________________________________________<br> <br> <br> <br> 7. Which one of the following has the highest IMF and why (explain in space below), H<sub>2</sub>O , CH<sub>3</sub>CH<sub>2</sub>OH, or NH<sub>3</sub>.<br> <br> <br> <br> <br> 8. Define evaporation including where and when does it occur?<br> <br> <br> <br> <br> 9. Explain why the more detailed definition of Boiling point is the temperature where the vapor pressure of the liquid = atmospheric pressure.<br> <br> <br> <br> <br> <br> <br> 10. Crude oil is a mixtures of compounds. Two of these compounds are hexane (C<sub>6</sub>H<sub>14</sub>) and octane (C<sub>8</sub>H<sub>18</sub>). What is the physical process called that separates these two liquid? What property is this physical process based on? Both of these substance have _________________ IMF. Which one has the higher IMF and why? Which one boils first? <br> <br> <br> <br> <br> <br> <br> <br> <br> 11. In heating a substance from its solid through boiling away all the substance, the portion that requires the greatest amount of energy is _________________. In the space below, explain why.<br> <br> <br> <br> <br> <br> <br> <br> 12.
