Since ethyne burns with a very hot flame, one of its most notable applications is in oxyacetylene gas welding and oxyacetylene gas cutting. Avec ses deux atomes de carbone, il se range aux côtés de l'éthane (CH3-CH3) et de l'éthanol (CH3-CH2OH, l'alcool des boissons). It has a triple bond between the two carbon atoms: one sigma bond and two pi bonds. Ethylene (IUPAC name: ethene) is a hydrocarbon which has the formula C 2 H 4 or H 2 C=CH 2.It is a colorless flammable gas with a faint "sweet and musky" odour when pure. Avec sa double liaison C=C, c'est un alcène, et le plus simple d'entre eux puisqu'il n'y a qu'une liaison. Par exemple, sa polymérisation produit le polyéthylène (PET), une matière plastique très commune. It can also be noted that the bond length of the carbon-hydrogen bond in the ethyne molecule is roughly equal to 106 picometres whereas the carbon-carbon bond length in the molecule is approximately equal to 120.3 picometres. C'est ainsi que l'on peut polymériser l'éthylène en accrochant les molécules les unes aux autres. In many cases, a single Lewis structure fails to explain the bonding in a molecule/polyatomic ion due to the presence of partial charges and fractional bonds in it. It is unstable in its pure form and thus is usually handled as a solution. A chemical formula of Ethyne can therefore be written as: C2H2 The chemical formula of Ethyne shown above is based on the molecular formula indicating the numbers of each type of atom in a molecule without structural information, which is different from the empirical formula which provides the numerical proportions of atoms of each type. Lewis structure represents every nonbonding valence electron with a dot, but that doesn't apply for ethyne because there are no nonbonding valence electrons.
