Which of these substances is likely to have the strongest cohesive forces? A) HBr B) CH₃F C) CH₃OH D) CH₃OCH₃ E) SiH₄

Question

Quizplus · Accepted Answer

Cohesion is the force of attraction between molecules of the same substance. In this case, we are comparing the cohesive forces between molecules of HBr, CH₃F, CH₃OH, CH₃OCH₃, and SiH₄. Among these, CH₃OH is likely to have the strongest cohesive forces because it can form hydrogen bonding between its polar molecules, which is a stronger intermolecular force than the dipole-dipole forces in HBr, CH₃F, and CH₃OCH₃. SiH₄ is a covalent compound and does not have intermolecular forces like hydrogen bonding, so it is unlikely to have the strongest cohesive forces.
