Consider the catalytic and chemical reductions of 2-pentyne. Which of the following statements is/ar — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Lindlar's catalyst (poisoned Pd) prevents full reduction to alkane and, because both hydrogens bind from the metal surface, forces Syn-addition yielding cis-alkenes. Thus, statement D is completely false. Standard $Pd/C$ causes full saturation to alkanes. Birch reduction causes Anti-addition to trans-alkenes.
