Question

Quizplus · Accepted Answer

Complete hydrogenation of 1-octyne, 2-octyne, and 3-octyne would fully saturate these molecules, converting each into octane, an alkane with no double or triple bonds. Since all three would be converted into the same molecule, octane, there is only 1 distinct product.
