Alkyne Synthesis Reactions Practice Problems

The first practice problem is a summary of alkyne reactions, followed by comprehensive synthesis practice problems; all the major classes of alkyne and alkene reactions are covered!
These include the preparation of dialkyl halides and their use in the preparation of Alkynes by Elimination Reactions, Hydrohalogenation, Hydration, Hydroboration–Oxidation, Ozonolysis, and other reactions of Alkynes and Alkenes, including the Zaitsev and Hoffman elimination reactions.

In addition, the synthetic strategies of changing the position of the double bond and extending the carbon chain by Alkylation of Terminal Alkynes are also demonstrated.

These examples guarantee a mastery level of alkyne and alkene reactions!
