Quiz Answer Key and Fun Facts
1. This is a common procedure used to separate organic compounds and to monitor a reaction's progress. It's also used to determine solvent systems for purification on a column. An organic chemist armed with a pencil, a chamber containing organic solvent, and a special plate can perform this easily.
2. This type of spectroscopy is mainly used to tell functional groups within a compound. Older versions require special salt plates, but newer technology has made them obsolete. The "fingerprint region" in the readout is only useful for those who have studied this method extensively, and isn't very useful for beginners.
3. This is a polar solvent used mainly to clean glassware since it dissolves things that soap and water cannot. It's such a good solvent, that it is sometimes used as the active ingredient in nail polish remover.
4. This noble gas is used in the practice of organic chemistry when reactions need to be kept dry and out of the atmosphere.
5. This is a polar solvent and also the intoxicating chemical compound in vodka, rum, wine, beer, etc.
6. This organic compound is often used to azeotrope water out of a solution. This is done by boiling the mixture or removing the mixture of solvents under vaccuum. The water will come off easier with this solvent even though they have different boiling points because they form this special mixture. It is a good solvent made up only of hydrogen and carbon. It is also used as an octane booster in gasoline.
7. This compound is used in organic synthesis as a base, most often in the preparation of esters and amides from acyl chlorides. It is also the active ingredient in FlyNap, a chemical used to anesthetize a type of fly.
8. All of the isotopes below can be seen using Nuclear Magnetic Resonance (NMR) except:
9. During a synthetic scheme, it is often necessary to protect a functional group to prevent unwanted reactions. Although there are many protecting groups available, this element often appears in protecting groups. Its affinity for fluorine allows it to be removed easily.
10. Refluxing or boiling a reaction in any solvent requires this kind of special glassware to prevent the solvent from evaporating and causing the reaction to dry out.
