Ph of ethyne

WebbEthyne is an alkyne, a class of substances which contain a carbon-carbon triple bond. When alkynes first undergo an addition reaction, one of the 𝜋 bonds between the carbon atoms can break and two new substituents can be added to the molecule. In the case of water addition, the two new substituents are a hydrogen atom and a hydroxy group.
