Reduction of alkynes
Electrophillic addition yields Markovnikov stereochemistry. Peroxide presence yields
anti-Markovnikov products by free radical addition. Markovnikov's rule: Electrophilic
addition to a C-C double bond involves the formation of the more stable carbocation.
(In ionic addition of an acid to a carbon-carbon double bond, the hydrogen attaches
itself to the carbon that already holds the greater number of hydrogens).
