Question

Place the following compounds in order of increasing strength of intermolecular forces. CH₄ CH₃(CH₂)₃CH₃ CH₃CH₃ A) CH₃(CH₂)₃CH₃ < CH₄ < CH₃CH₃ B) CH₃(CH₂)₃CH₃ < CH₃CH₃ < CH₄ C) CH₃CH₃ < CH₄ < CH₃(CH₂)₃CH₃ D) CH₄ < CH₃(CH₂)₃CH₃ < CH₃CH₃ E) CH₄ < CH₃CH₃ < CH₃(CH₂)₃CH₃

Quizplus · Accepted Answer

The order of increasing strength of intermolecular forces is determined by the type and size of molecules. CH4 (methane) has the weakest forces due to its small size and lack of polarity. C2H6 (ethane) has slightly stronger forces due to its larger size but is still nonpolar. C2H5OH (ethanol) has the strongest forces because it can form hydrogen bonds due to the presence of an -OH group, in addition to London dispersion forces and dipole-dipole interactions.
