Question
These compounds can be partially reduced by sodium metal in liquid ammonia to produce a trans product. For 10 points each:
[10h] Name this functional group, whose terminal variety has a pKa of about 26. The Corey-Fuchs (FEWKS) reaction produces these compounds from aldehydes.
ANSWER: alkyne
[10e] Alkynes are characterized by having one of these bonds, which contain one sigma and two pi bonds and are designated by three lines on a molecular structure.
ANSWER: triple bonds
[10m] If you want the cis product instead, alkynes can be reduced by using this catalyst, which contains palladium on calcium carbonate, poisoned by lead oxide or quinoline.
ANSWER: Lindlar's catalyst
