So we know sodium amide being a strong … WebThe alkynes are unsaturated hydrocarbons that contain one triple bond, the general formula of alkynes CnH2n-2 and the triple bond is known as the ‘acetylenic bond’. Many alkynes have been found in nature. Ethyne (C2H2) is the first member of the alkyne family, with two carbon atoms connected by a triple bond.

Did you know?

WebAlkynes are known to be compounds that have triple bonds in the molecule. While many compounds have the structure of alkanes and alkenes, there are also compounds that have triple bonds in the molecule. Unlike single and double bonds, triple bonds have special properties. For example, due to their high acidity, they can be used … WebA fatty acid that has two or more double bonds between carbon atom chain.
