My report on "Intermolecular Attractions" Student name: Kenny Sorensen Teacher name: Dr. T School: Quincy High School Submission Time: 3/25/12 8:12 PM Page 1 : http://mw2.concord.org/public/part2/vdw/page1.cml 1. What is the difference between polar and non-polar molecules? (Be sure to include more than the colors used to represent them in your response!) non-polar molecules contain bonds in which elecrons are equally shared while polar molecules contain bonds that have unequally shared electrons causing partially positive and partially negative charges on the molecule's surface. (7:41:37 PM) 2. Image showing intermolecular attractions: image showing intermolecular attractions(8:03:22 PM) 3. Which of the following formed intermolecular attractions (check all that apply): (a) + ends of polar molecules to + ends of other polar molecules (b) + ends of polar molecules to - ends of other polar molecules (c) - ends of polar molecules to - ends of other polar molecules (d) non-polar molecules to other non-polar molecules (e) non-polar molecules to + parts of polar molecules (f) non-polar molecules to - parts of polar molecules My answer is (b) (d) (e) (f)(7:45:10 PM) Page 2 : http://mw2.concord.org/public/part2/vdw/page2.cml 1. What is the primary attraction between NON-POLAR molecules: (a) (b) (c) (d) London Dispersion attraction dipole-dipole attraction gravitational attraction magnetic attraction My answer is (a)(7:49:43 PM) 2. What is the primary attraction between POLAR molecules: (a) London Dispersion attraction (b) dipole-dipole attraction (c) gravitational attraction 1 (d) magnetic attraction My answer is (b)(7:49:49 PM) 3. Which type of intermolecular attraction is strongest: (a) (b) (c) (d) London Dispersion attraction dipole-dipole attraction gravitational attraction magnetic attraction My answer is (b)(7:49:56 PM)
