87. Chemistry 1B / Lecture C / Nonbonding Forces Summary Many lectures on chemistry, including bonding concepts and data. http://eee.uci.edu/97w/40090/nonbond.html

Chemistry 1B Lecture C ( Grayce ) Winter 1997 Nonbonding Forces Summary Recall the first part of this course is all about the forces between molecules that are induced by the way in which the electrons distribute themselves around nuclei. In some cases the electrons are shared between nuclei and they induce powerful chemical bonding forces that join nuclei into molecules. But even when the electrons don't cause an actual chemical bond to form, they still induce nonbonding forces that cause atoms or molecules to influence each other. They may orient with respect to each other, like carbon monoxide molecules do when near each other, or they may simply cause attractions that make it harder to disperse the molecules apart (boil a liquid, say). Here's a table outlining the nonbonding forces we have studied. In each case `` E'' stands for a rough estimate of the total amount of energy released (that is, the decrease in the energy of the system) when the objects in question (ions, dipoles, whatever) come from very far away from each other to close by. You should keep in mind when considering these figures that an ordinary covalent chemical bond has a bond energy of about 400 kJ/mol. force acts between: E consequences ion-ion ions only 1000 kJ/mol ionic crystals ion-dipole 100 kJ/mol solvation shells dissolution dipole-dipole dipoles only 3 kJ/mol polar liquids boil at higher temps than nonpolar London anything 1 kJ/mol (for < 6 light atom molecules; can be more for big molecules, big atoms)

Below the table there is a " Chemical Elements Sorted By " section with links that will sort chemical elements by various properties. What's New Don't like banner ads? Well neither do we, but they are the most effective method for us to generate the revenues necessary to operate this site while making our content available free of charge. Now, however, we have an option that will reward those who directly support our efforts with the ability to access this site banner ad free. SUBSCRIBE TODAY Many elements now include a page of common chemicals and chemical formulas that contain the given element. These chemical compounds in turn are linked to a page that contains more information on the chemical compound. As the underlying chemical database is a work in process, some chemicals will have very detailed information while others will have only basic information. If you know of resources (including public domain databases, or financial grants that would allow us to license databases); or are responsible for a database of chemical compounds and would like to partner with EnvironmentalChemistry.com; please contact us. Of particular short term interest to us is a table of data that cross references chemical formulas to CAS Numbers and/or chemical names.

I am using them with beginning students in organic chemistry as educational aids and in tutorials on this site. I use a commercial programme to obtain x,y,z coordinates and convert these into the pbd format by first using the format interconversion programme, Babel, then using a Perl script followed by hand editing to produce the final pdb file. pdb files may be viewed using the ChemScape Chime plug-in or by using the stand-alone programme Rasmol (This site also has lots of information on RasMol, Chime and Protein Explorer.)
