Hydrogen Bonding

Hydrogen Bonding A particularly important type of dipole-dipole interaction is hydrogen bonding. It’s the main reason for the stability of the double-helix secondary structure of DNA, the unusual phase diagram of water, and the secondary structure of proteins in our bodies. Strictly speaking, hydrogen bonds are a special case of Read more…

Ion-Dipole Interactions and Hydrophilicity

Ion-Dipole Interactions and Hydrophilicity Ion-dipole forces are generally stronger than dipole-dipole interactions because at least one of their participants is an ion, which means it has a net electric charge, whereas dipole-dipole forces involve polar molecules with no net electric charge. These interactions explain why ionic compounds tend to be Read more…

Dipole-Dipole Interactions

Dipole-dipole interactions Many covalently bonded molecules have a net neutral electric charge, but do not distribute their charge evenly. Some parts of their structure have greater electron density than others. This is again a result of differences in electronegativity. For example, chlorine is more electronegative than carbon. Consequently, bonds between Read more…

Ion-Ion Interactions

Ion-ion interactions Recall that ions are atoms or molecules that have lost or gained one or more electrons with respect to their electrically neutral counter-parts, such that they have a net electric charge. As a result, two or more ions can exert electrostatic forces on each other. This is the Read more…
