The correct answer is option (2) Na/Liq.NH₃.
Explanation:
- Na/Liq.NH₃ will yield trans products from butyne.
- Reduction of alkynes with liquid NH3/Li gives trans alkenes.
- The reduction of alkynes to alkenes is done with the help of sodium in liquid ammonia. This catalyst readily gives the trans-2-Butene (E-2-Butene).
- Among all the options, Na/Liq.NH₃ will yield trans products from butyne.
