\( 2 \)-butyne is reduced to trans-but-2-ene using
- A\( H_{2} \mid P d-C \)
- B\( \mathrm{Zn} \) in dil. \( \mathrm{HCl} \)
- C\( \mathrm{OH}_{2} \mid \mathrm{Ni} \)
- Correct answerD\( \mathrm{Na} \) in liq. \( \mathrm{NH}_{3} \)
Solution
(D)
Birch reduction
\[ =\frac{\mathrm{Na}_{\mathrm{a}}}{\operatorname{liq}_{\mathrm{in}} \mathrm{NH}_{3}}= \]
Birch reduction
\[ =\frac{\mathrm{Na}_{\mathrm{a}}}{\operatorname{liq}_{\mathrm{in}} \mathrm{NH}_{3}}= \]
Hence, the correct answer is option: 'D'.
