Lab – Properties of Alcohols

1. What are the specific hazards associated with the alcoholsused in this experiment? What are the specific hazards associatedwith the chromic acid reagent?

2. Consider the alcohol hexyl alcohol (1-hexanol), C6H14O. Drawboth a structural formula and a condensed structural formula for1-hexanol. Identify 1-hexanol as a primary, secondary, or tertiaryalcohol.

3. What would you expect to observe if you performed the chromicacid test on a sample of 1-hexanol?

4. What would you expect to observe if you performed the Lucastest on a sample of 1-hexanol?

5. Aqueous solutions of isopropyl alcohol are commonly sold asrubbing alcohol. The boiling point of isopropyl alcohol is 82.4 °C.It evaporates readily from the surface of the skin. Ethylene glycol(CH2OHCH2OH) is sold as antifreeze/antiboil. The boiling point ofethylene glycol is 198 °C. The molecular masses of isopropylalcohol and ethylene glycol are similar. Provide an explanation forthe observed difference in their boiling points

6. Chromic acid oxidation is the basis of the Breathalyzer Testused by many police departments to detect ethyl alcohol in thebreath of people suspected of driving under the influence. Theamount of the green product is proportional to the amount of ethylalcohol in the breath. Write structural formulas for the twooxidation products formed from ethyl alcohol. Name the oxidationproducts.

7. If you exercise strenuously without sufficient oxygen, lacticacid accumulates and contributes to muscle fatigue and soreness.When oxygen is later available, lactic acid must be oxidized topyruvic acid. The structure of lactic acid is shown below.

(a) Circle the alcohol functional group. Classify the alcohol asprimary, secondary, or tertiary.

(b) Predict the solubility and chromic acid test results forlactic acid.

(c) Complete the reaction equation above. Draw the formula ofthe reaction product, pyruvic acid.
