WebIn this review, the term acetylene is used in its narrow sense and refers exclusively to C2H2; all other organic molecules bearing a triple C–C bond are termed substituted alkynes or higher alkynes. In the literature, one often refers to “acetylenes” in the latter cases. WebAcetylene is a compound of the elements carbon and hydrogen. Its composition is expressed by the chemical symbol C2H2. On a weight basis, the proportion of the elements in acetylene is approximately 12 parts of carbon to 1 part of hydrogen, or 92.3% to 7.7%, respectively. Physical and chemical properties
