The molecules in solid PH₃ are attracted to each other by ___. A) London dispersion forces B) hydrogen-bonding C) dipole-dipole interactions D) London dispersion forces and dipole-dipole interactions E) London dispersion forces and hydrogen-bonding

Question

Quizplus · Accepted Answer

Solid PH₃ has both polar covalent bonds and nonpolar covalent bonds. Polar covalent bonds result in the formation of dipoles, leading to dipole-dipole interactions between neighboring molecules. Nonpolar covalent bonds only result in London dispersion forces. Therefore, since solid PH₃ contains both polar and nonpolar covalent bonds, it is attracted to other molecules by both dipole-dipole interactions and London dispersion forces.
