Exercise 7) Make a molecular model of C2H6O. Now make another molecular model that is
different from the first one (but don't take that one apart yet).
Draw the structural formulas for both of your models in the space below, then write the
condensed formula below each structure.

- Exercise 12) Draw the structural formulas for all of the structural isomers of C4H8. Hint: There are six structural isomers. Using models can be very helpful with this one. Remember, to be an isomer you have to actually break apart a bond. If you can simply rotate one of your models and get the same shape it is not an isomer (that's called a conformation)!
