Reac Con Compare the odors of the hydrocarbons. Did you notice an odor trend among the types of hydrocarbons? Comment. bur On pro Were the hydrocarbons soluble in water? In methylene chloride? What is your evidence that they dissolve in one solvent and not in the other? d. Tea R Explain why they dissolve in one solvent, but not in the other. Paraffin wax is primarily a mixture of long-chain hydrocarbons, an example of which is CH52. Draw the structure of a molecule found in this mixture. How do the odors of the cyclic hydrocarbons and paraffin compare? How do you explain the tremendous difference in intensity of the odors of paraffin and the cyclic hydrocar- bons? 2.
