Definition: A single bond is a chemical link between two atoms in which electrons are shared between them. Examples: There is a single bond between the oxygen and each hydrogen in a water molecule (H 2 O). Each of the covalent bonds contains two electrons-one from a hydrogen atom and one from the oxygen atom.
So it is possible to have 2-pi bonds and a sigma or what we call a triple bond. In conclusion, a triple bond is a sigma bond located directly between the atoms, and 2 pi bonds located above and below, and around the sides of the 2 atoms. Every bond has a sigma. Doubles have a sigma and a pi. Triples have a sigma and two pi bonds.
