Indicate which of the following nonpolar compounds will have the lowest boiling point. A)CCl₄ B)CI₄ C)CF₄ D)CH₄ E)CBr₄

Question

Quizplus · Accepted Answer

The boiling point of nonpolar compounds is determined by the strength of the intermolecular forces of attraction, specifically the van der Waals forces. The larger the molecule, the more electrons it has and the stronger the van der Waals forces. Among the given options, CH4 has the smallest molecular size and hence the weakest van der Waals forces, and thus, will have the lowest boiling point.
