2. A student tested an unknown compound for solubility and found that the compound was soluble in hexane, but not soluble in water.
a. Choose (X) the one statement below that best expresses the conclusion of this solubility test.
The unknown compound is polar.
The unknown compound is non-polar.
The polarity of the unknown compound cannot be determined by this test.
b. If the unknown compound was either ethanol or 1-hexanol, could these solubility tests distinguish which type of compound is the correct one? Explain.
3. Briefly describe one chemical test that could distinguish between an alkane and an alkene. Describe what result would be observed for an alkane and for an alkene.
