Final answer:Theboiling pointof a molecule is influenced by the strength of the forces between its molecules. In the given sets, H2O has the highest boiling point in the first due to its capability of forming hydrogen bonds. Hexane has the highest boiling point in the second set due to its larger size and greater number of electronsExplanation:The boiling point of a molecule is influenced by the strength of the forces between its molecules. This includes London dispersion forces, dipole-dipole interactions, and hydrogen bonding. Substances with stronger intermolecular forces generally have higher boiling points because more energy is needed to break those forces.In your question, you need to consider both sets of molecules separately. In the first set,H2Ohas the highest boiling point due its ability to form hydrogen bonds, which are strong intermolecular forces. In the second set,hexanewould have the highest boiling point due to its larger size and greater number of electrons, which increases the strength of its London dispersion forces.Learn more aboutBoiling Pointhere:brainly.com/question/34261956#SPJ11...
