#16

**Molecules and Intermolecular Forces** The following questions relate to the molecular structures provided below. Use these molecules to answer questions 14-17. **Molecular Diagrams:** - **Molecule A**: - Formula: SiF₄ - Structure: A central silicon (Si) atom bonded to four fluorine (F) atoms arranged tetrahedrally, with lone pairs on each fluorine atom. - **Molecule B**: - Formula: C₂H₆ - Structure: Two carbon (C) atoms bonded together with single bonds to three hydrogen (H) atoms on each carbon, forming a linear structure. - **Molecule C**: - Formula: C₂H₄O₂ - Structure: A carbon (C) atom double-bonded to an oxygen (O) atom and single-bonded to another carbon. This carbon is also bonded to two hydrogen atoms and another oxygen atom, which is bonded to hydrogen (forming an alcohol group). **Questions:** 14. **Which molecule(s) is/are polar?** A) A B) B C) C D) B and C E) A and C 15. **What is the strongest type of intermolecular force present in B?** A) Ion-dipole B) London dispersion C) Hydrogen bonding D) Dipole-dipole E) None of the above 16. **Which molecule has the lowest boiling point?** A) A B) B C) C D) A and C E) All have the same boiling points.
