Which of the following molecules would probably be isolated closest to the bottom of a fractionating tower at a refinery?

Question

Quizplus · Accepted Answer

In a fractionating tower at a refinery, molecules with higher molecular weights (and typically longer carbon chains) have higher boiling points and are therefore isolated closer to the bottom of the tower. C40H82 has the longest carbon chain and the highest molecular weight among the options, making it the molecule most likely to be found at the bottom.
