Multiple Bond Definition in Chemistry

In chemistry, a multiple bond is a chemical bond where two or more electron pairs are shared between two atoms. Double and triple bonds are multiple bonds. In a double bond, four bonding electrons participate in the bond rather than two electrons in a single bond. Double bonds are found in azo compounds (NN), sulfoxides (SO), and imines (CN). The equal sign is typically used to denote a double bond. A triple bond involves six bonding electrons. The triple bond is drawn using three parallel lines (≠¡). The most common triple bond occurs in alkynes. Molecular nitrogen (N2) is an excellent example of a compound with a triple bond (N≠¡N).Triple bonds are stronger than double or single bonds.
