Quizplus · Accepted Answer

The reduction of an alkyne with Li/NH3 followed by water produces the corresponding trans-alkene. Therefore, the correct product in this case is Z-2-pentene, not pentane. The other two answer choices are correct, as they both produce the expected reduction products. Therefore, option D is not correct because it implies that all answer choices are correct.
