List the species (e.g. ionic, metallic, polar, etc) from highest IMF to lowest IMF<br> ____________________________________________<br> <br> <br> <br> 10. What are the two IMF names for polar molecules interacting with each other? _____________ and ________________<br> <br> 11) London Dispersions force (caused by uneven distribution of electrons for very short period of time, called Instantaneous dipole) exist for all species? Yes or No?<br> <br> <br> 12) Can an ionic compound (i.e. a set of ions) be polar or non-polar? Explain why or why not.<br> <br> 13) Pyramidal geometry is symmetrical, True or False (Circle one).<br> <br> <br> 14) 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> 15) 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 (look up in Internet)? 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> 16) Using your knowledge of IMF, explain why vegetable oil and water do not mix or do not dissolve in each other.<br> <br> <br>
