Chapter 13: Alkynes

Reaction #1: Synthesizing alkynes by double dehydrohalogenation
-Turns Alkane with two halogen leaving groups into a alkyne using strong base (NH2) 

Note: Nasiri does not use "mineral oil" in her dehalogenations. 
For the second reaction (geminal dihalide), rather than using excess NaNH2 and heat, Nasiri writes two steps: 1.) 3 equivalents of NaNH2  2.) H2O

Reaction #2: Reduction of alkynes by catalytic hydrogenation
-Turns Alkyne into either an alkane, cis alkene, or trans alkene (depending on reagent)

---

Reaction #3/4: Halogenation and Hydrohalogenation of alkynes

---

Note: we can form a Grignard's reagent or Cuprate reagent from a haloalkene

Reaction #5: Addition of OH to alkyne
First Video = Markovnikov addition of OH and Acid-catalyzed tautomerization

Second Video = Anti-Markovnikov addition of OH and base-catalyzed tautomerization
