Question
The heat associated with the melting process is called the: A. Heat of Vaporization B. Heat of Combustion C. Heat of Fusion D. Heat of Condensation Which of the following would have the highest boiling point? A. N_2 B. Br_2 C. H_2 D. CI_2 E. O_2 When NaCI dissolves in water, aqueous Na^+ and CI^- ions result. The force of attraction that exists between Na^+ and H_2O is called a(n) ____ interaction. A. Dipole-Dipole B. Ion-Ion C. Hydrogen Bonding D. Ion-Dipole E. London Dispersion Force Elemental iodine (I_2) is a solid at room temperature. What is the major attractive force that exists among different I_2 molecules in the solid? A. London Dispersion Forces B. Dipole-Dipole rejections C. Ionic-Dipole interactions D. Covalent-Ionic interactionsExplanation / Answer
2) helium atom will have only weak london dispersion forces due to absence of any polarity.
5) all the given molecules are non polar and will have only weak london dispersion forces
However Bromine has biggest size which increases the intermolecular forces and hence make the boiling point of Bromine highest among given molecules
6) the attraction between Na+ with H2O, is ion dipole interaction
7) There are london dispersion forces in iodine molecule
