Chapter 10: States of Matter - Exercises [Page 158] Q 3. Note: For similar substances, London dispersion forces get stronger with increasing molecular size. Like a dipoleinduced dipole force, the charge of the ion causes distortion of the electron cloud on the non-polar molecule. The number of Hydrogen bonds formed between molecules is equal to the number of active pairs. Using a flowchart to guide us, we find that O2 only exhibits London Dispersion Forces since it is a non-polar molecule.In determining the intermolecular forces present for O2 we follow these steps:- Determine if there are ions present. A. E. Douglas and C. K. Mller, J. Chem. Instantaneous dipoleinduced dipole interactions between nonpolar molecules can produce intermolecular attractions just as they produce interatomic attractions in monatomic substances like Xe. Answered: The rate constant for the first-order | bartleby To predict the relative boiling points of the other compounds, we must consider their polarity (for dipoledipole interactions), their ability to form hydrogen bonds, and their molar mass (for London dispersion forces). Intermolecular Forces for H2O (Water) - YouTube Thermal decomposition of core-shell structured HMX@Al nanoparticle (H) The structures of ethanol, ethylene glycol, and glycerin are as follows: Arrange these compounds in order of increasing boiling point. Interactions between these temporary dipoles cause atoms to be attracted to one another. The interaction has its immense importance in justifying the stability of various ions (like Cu2+) in water. These intermolecular interactions are strong enough to favor the condensed states for bromine and iodine under normal conditions of temperature and pressure. Determine the intermolecular forces in the compounds and then arrange the compounds according to the strength of those forces. For example, it requires 927 kJ to overcome the intramolecular forces and break both OH bonds in 1 mol of water, but it takes only about 41 kJ to overcome the intermolecular attractions and convert 1 mol of liquid water to water vapor at 100C.
