An alkyne undergoes partial reduction with Lindlar catalyst (Pd/BaSO₄, quinoline) to give an alkene product. If the same alkyne is instead treated with Na/NH₃ in liquid ammonia, a different alkene stereoisomer is obtained. What is the fundamental difference between these two reduction methods that accounts for the stereochemical divergence?
