  2. Click on a question to begin

  3. Question 1

  4. Try Again • Strong intermolecular forces lead to high boiling points and low freezing points Try Again

  5. Correct! • H2O has the highest boiling point so it must have the highest intermolecular forces Next Question

  6. Question 2

  7. Try Again • Dipoles (polar molecule) occur when a molecule is not symmetric Try Again

  8. Correct! • H2S is not symmetric so it will have a dipole Next Question

  9. Question 3

  10. Try Again • To determine polarity you must compare the electronegativity of the two atoms in the bond Try Again

  11. Correct! • Fluorine and fluorine have the same electronegativity so they form a non-polar bond. This also means it is a non-polar molecule. Next Question

  12. Question 4

  13. Try Again • Electronegativity increases to the right and top of the periodic table. Try Again

  14. Correct! • Chlorine is closer to the top right of the periodic table, so it has a higher electronegativity. This means the electrons will move closer to chlorine than hydrogen. Next Question

  15. Question 5

  16. Try Again • Most polar means biggest difference in electronegativity Try Again

  17. Correct! • H and O are the furthest apart on the periodic table and have the biggest difference in electronegativity Next Question

  18. Question 6

  19. Try Again • Non-polar bonds will have an electronegativity difference of less than 0.4 Try Again

  20. Correct! • Br – Br has an electronegativity difference of zero so it is non-polar Next Question

  21. Question 7

  22. Try Again • Both molecules have covalent bonds so the difference is in the intermolecular forces Try Again

  23. Correct! • Water contains oxygen so it has the ability to form hydrogen bonds Next Question

  24. Question 8

  25. Try Again • Stronger intermolecular forces cause a substance to stay in a more structured state Try Again

  26. Correct! • Fluorine has weaker intermolecular forces and therefore is a gas while iodine is a solid Next Question

  27. Question 9

  28. Try Again • Polarity is determined by the amount that each atom in a bond wants electrons Try Again

  29. Correct! • Difference in electronegativity determines whether or not a bond will be polar Next Question

  30. Question 10

  31. Try Again • Only the three most electronegative atoms on the periodic table are capable of hydrogen bonding Try Again

  32. Correct! • Oxygen, Nitrogen and Fluorine are the only three atoms that can hydrogen bond Next Question
