9. Category 2
VSEPR shapes

10. Challenge 1
Be the first person to draw a molecule with a bent shape.

11. Challenge 1 answer

12. Challenge 2
Be the first person to draw the Lewis dot structure for an NH3 molecule and identify the vsepr shape.

13. Challenge 2 answer
Trigonal Pyramidal

14. Challenge 3
Draw the Lewis dot structure of a HCN molecule and identify the vsepr shape

15. Challenge 3 Answer
Linear

16. Category 3
Polarity

17. Challenge 4
Draw the Lewis dot structure of H2S and display the polarity of the bonds

18. Challenge 4 answer

19. Question 4
What is defined as a molecule that has a more positively charged side and a more negatively charged side?

20. Answer 4
Dipole

21. Challenge 5
Draw the Lewis dot structure of a CF3H molecule and justify whether or not it is polar.

22. Challenge 5 Answer
The molecule is polar because the individual polarities of the bonds do not all cancel out, causing the molecule as a whole to exhibit a polarity.

Which intermolecular force (IMF) is present in all polar molecules?

25. Answer 6
Dipole interactions

26. Question 7
Which of the intermolecular forces occurs between an electronegative atom on one molecule and a partially positive charged hydrogen on another molecule?

27. Answer 7
Hydrogen bonding

28. Question 8
Which intermolecular force is caused by the movement of electrons?
