What is another word for acetylene?
Pronunciation: [ɐsˈɛtəlˌiːn] (IPA) 
Acetylene is a hydrocarbon gas that is commonly used as a fuel for welding and cutting. It is also known by several other names such as ethyne, vinylene, and dimethylacetylene. Ethyne being a widely used synonym, is derived from its chemical identity as an alkyne with two carbon atoms. Vinylene comes from the fact that the gas is composed of two carbon atoms joined together by a double bond, similar to vinyl chloride molecules. Dimethylacetylene is a more complex and less commonly used synonym that refers to the gas's chemical structure, which includes two methyl groups attached to one of the carbon atoms. All these synonyms ultimately refer to the same compound, acetylene.
