Draw expanded structural formulas for the following organic compounds.  If you prefer, you can use hash marks (lines) to indicate the hydrogen in each. Draw your structures on a separate sheet of paper and immediately after submitting the exam, take a picture of your work and upload it into the Final Exam Pictures link located in Final Exam module in Canvas. Please make sure to number each structure.  1)   2,3,3-trimethyl-1-hexene 2)  3-ethyloctane 3)  CH3(CH2)5CH3 4)  Draw a structural isomer of pentane (must be a compound other than pentane) and Correctly name the compound that you draw.
