What is the major organic product that results when 3-heptyne is treated with sodium metal in ammonia?

Question

Quizplus · Accepted Answer

When 3-heptyne is treated with sodium metal in ammonia, it undergoes a dissolving metal reduction (DMR) reaction, which reduces the triple bond to a double bond. The resulting product is 3-heptene, which exists in both the Z and E isomers. However, since the reaction is stereospecific, meaning that it preserves the stereochemistry of the starting material, the major product will be the E isomer, as the starting material is E-3-heptyne. Therefore, the correct answer is (E)-3-heptene (option D).
