- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: B —
Solution
- The reduction of alkynes to trans-alkenes is a stereoselective reaction.
- Sodium in liquid ammonia provides solvated electrons for the reduction.
- This process follows an anti-addition mechanism.
- Hence the answer is (B).
