Quick Summary

A multiple bond in chemistry occurs when two atoms share more than one pair of electrons. This results in a double bond, represented by two parallel lines (=), or a triple bond, shown as three parallel lines (≡). Double bonds involve two shared electron pairs (four electrons total), while triple bonds involve three shared electron pairs (six electrons total). These multiple bonds are stronger than single bonds and are found in various compounds, including carbon dioxide, nitrogen molecules, and acetylene. Carbon's unique ability to form extensive networks of covalent bonds, including multiple bonds with itself, is fundamental to the diversity of organic compounds essential for life.1234
