Reduction of Alkyne:
Alkynes add on hydrogen in existence of appropriate catalysts like finely divided Ni, Pd.
Determine if the triple bond is not found at the end of the carbon chain of the molecule, the alkene made may be cis and trans depending upon the choice of reducing agents.
With Na/NH3 or LI / NH3 in (liquid ammonia) trans alkene is approximately an exclusive product whereas catalytic reduction at alkyne affords mainly cis alkenes.
