Given the three statements below, pick the best answer.
I. Dipole-dipole forces are the main intermolecular force for I - Br.
II. O₂ is a gas at room temperature because it is highly polarizable.
III. London forces dominate the intermolecular forces for Br₂.

Question

Quizplus · Accepted Answer

Statement I is false because I-Br molecule does not have a permanent dipole moment. Statement II is also false because O₂ is actually a liquid at room temperature despite being highly prone to polarizability. Statement III is true because Br₂ is a nonpolar molecule that only experiences London dispersion forces. Therefore, only III is true.
