Alkyne Reactions:
Using Lindlar's catalyst results in syn addition to form a cis alkene. Using lithium in liquid ammonia yields a trans alkene Ozonolysis Preparation of alkynes

Diene Reactions:
Adding HBr to a diene forms a 1-2 adduct (top) or a 1-4 adduct (bottom) Adding Br2 to a diene forms a 1-2 adduct (top) or a 1-4 adduct (bottom)
Alkene Reactions:
Creates a vicinal halide (anti addition) syn addition Creates an alkyl halide following Markovnikov's ru Creates a Markovnikov alcohol Creates an anti-Markovnikov alcohol Alkenes react with peracides to form epoxodies/oxiranes through a syn addition Yields two carbonyl compounds. React with cold potassium permanganate to form vicinal diols through a syn addition. Eliminates water to form the most stable alkene (use Zaitsev's rule) Eliminates HX to form the most stable alkene (anti elimination) (use Zaitsev's rule)
