As pure molecular solids,which of the following exhibits dipole-dipole intermolecular forces: HBr,NBr₃,SBr₂,and CBr₄? A) HBr only B) CBr₄ only C) HBr and SBr₂ D) NBr₃ and CBr₄ E) HBr,NBr₃,and SBr₂

Question

Quizplus · Accepted Answer

HBr, NBr3, and SBr2 all have polar bonds, which result in dipole moments. Therefore, they exhibit dipole-dipole intermolecular forces. CBr4 is a nonpolar molecule, so it does not exhibit dipole-dipole forces. Therefore, the correct answer is E, which includes all three polar molecules.
