Lesson Summary. Hydrogen bonds are formed when the positive end of a polar molecule is attracted to the negative end of a polar molecule. This can happen either between different molecules, as in intermolecular hydrogen bonds, and within a single molecule, as in intramolecular hydrogen bonds.
In general, there are two types of bonds. Sigma-bonds and pi-bonds. The electrons in a sigma bonds are concentrated along the line directly connecting two atoms. The electrons in a pi bond follow arc shaped geometry (above and below) the two bonded atoms. Because of this shape, pi bonds are sometimes called banana bonds.
