d. trans-2-butene

Answer:

Hydrogenation of Alkynes:
Alkynes can be hydrogenated in three different ways:
• Complete hydrogenation to an alkane utilizing H2 and a metal impetus, for example, Pd, Pt, or Ni
• Partial hydrogenation to a trans-alkene utilizing Na in NH3
• Partial hydrogenation to a cis-alkene utilizing H2 with Lindlar’s Catalyst

Explanation:
The principal response is hydrogenating an alkyne with H2 and Pd. This outcomes in a total hydrogenation to the alkane, which is spoken to by structure 3.
The subsequent response is hydrogenating an alkyne with Na and NH3. This outcomes in a fractional hydrogenation to a trans alkene, which is structure d, trans-2-butene.
