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.
A single bond is usually a Ï bond. Pi (Ï) bonds are weaker and are due to lateral overlap between p (or d) orbitals. A double bond between two given atoms consists of one Ï and one Ï bond, and a triple bond is one Ï and two Ï bonds. Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond.
