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…

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…
