tri·ple bond

a covalent bond resulting from the sharing of three pairs of electrons, for example, HCΞCH (acetylene).

tri·ple bond

(trip'ĕl bond)
A covalent bond resulting from the sharing of three pairs of electrons.

triple bond,

n a covalent bond in which three valence (outer) electrons are contributed from each participating atom, which results in a total of six electrons; represented in a chemical formula by three lines that join the participating atoms. See also covalent bond.
