A "hydrogen bond" is simply a particularly strong attraction between the bonded hydrogen atom and a lone pair on another atom. The intermolecular forces that attract molecules to each other are much weaker than the bonds that hold molecules together. Fore of O-H bonds in H20 molecules, but only 44 k/mol are needed to separate one mole of water molecules in liquid water xample, 463 kmol are required to break one mole Types of intermolecular forces: interaction between a hydrogen atom attached to an atom of fluorine, oxygen, or nitrogen on one molecule anda Hydrogen bonding: An electronegative is the strongest Intermolecular force. e paionogr sflectrons on a tuorne, oxygen, or nitrogen on another molecule. This Dipole-dipole forces: Often polar covalent bonds create polar molecules which have a posltive end and a negatlve end. The positlvely polarized ends of molecules will attract the negatively polarized ends of other molecules London dispersion forces: At any given instant, electrons may be nearer to one end of a molecule or the other. When they are nearer to one end, the nearby molecules, causing the ends of the molecules nearby to have a partial positive charge, and creating a momentary attractive force. This Is the weakest force and is present in all molecules. In large molecules, this force can be quite significant Critical Thinking Questions: 17.What is the difference between Intramolecular bonds and intermolecular forces? 18. Rank these intermolecular forces in terms of their typical relative strengths: dipole dipole, hydrogen bonding, London forces. Compare with your team. Intermolecular forces, write a consensus explanation of he general trend that you described in CTQ 13. 20.Suppose that we conslder anything over about 1 aram.per 100 ml water to be "soluble. What is the heaviest alcohol in Model 2 that is water soluble? b. a. How many carbons are In this alcohol? what is the heaviest amine in Model 2 that is water soluble? c. d. How many carbons are in this amine? 21. Considering your answers to CTQ 20, the presence of is sufficient to dissolve a molecule containing about how many nonpolar carbons? Circle one of the following choices: 1-2 3-4 5-6
