Quizplus · Accepted Answer

The molecule (3E,5Z)-3-methylhepta-3,5-dien-1-yne contains three types of unsaturations: one triple bond and two double bonds. Each double bond requires 1 mole of hydrogen to be reduced to a single bond, and the triple bond requires 2 moles of hydrogen to be fully reduced to a single bond. Therefore, in total, 4 moles of hydrogen are needed (2 for the triple bond + 1 each for the two double bonds).
