4. Build a model for pentane and orient the bonds so that your model looks like the dashed-and-wedged structure below. Use your model to help you complete problems a-c below. a. Rotate the bond betwece the secood and thind carbon in the model so that you create a different conformer of pentane. Draw a dashed-asd-wedged struchure for the cenformer you created below. b. Now rotate additional boods in your model to come up with one more conformer for pentane, and draw a dashod-and-wedged structure for your conformer below. c. Are the theee different drawings for this problem (inclading the computcrized drawing) regresenting different molecules? NOTE: Do not break down your modell It will save you time to keep this model and manigulate it as nooded for later problems. Written by A. Norick 14
