Alkynes are a family of hydrocarbons distinguished by having a minimum of one triple bond in their molecular structure between carbon atoms. Compared to equivalent saturated hydrocarbons with the same number of carbon atoms, they are unsaturated hydrocarbons because they have less hydrogen atoms.As a general rule, alkynes have the formula CnH2n-2, where "n" is the number of carbon atoms in the compound. Because of its triple bond, which can undergo a variety of chemical reactions, alkynes are frequently encountered in organic chemistry and are renowned for their reactivity. The acidity of alkynes is a noteworthy characteristic. In comparison to those in alkanes and alkenes, the hydrogen atoms bound to the carbon atoms of the triple bond are comparatively acidic. The triple bond's sp hybridized carbon atoms, which stabilize the resultant carbanion during deprotonation, are thought to be the cause of this acidity.Alkynes are capable of addition reactions, in which the carbon atoms of the triple bond are supplemented with one or more atoms. Among these reactions are hydrohalogenation, hydration, halogenation, and hydrogenation. Because of their high degree of unsaturation at the triple bond, alkynes are useful intermediates in chemical synthesis. The hydrogenation process, in which hydrogen gas is introduced across the triple bond in the presence of a catalyst—typically a metal catalyst like palladium or platinum—is one of the most well-known reactions involving alkynes. Alkynes are changed into alkanes by this process.Depending on the circumstances and the make-up of the reactants, alkynes can also go through hydration, a reaction in which water molecules add across the triple bond to generate ketones or aldehydes. Mercuric salts or strong acids catalyze this process.The creation of alkynes from haloalkanes or other alkynes is another significant alkyne reaction. The Corey-Fuchs reaction is a chemical reaction that occurs when a haloalkane is treated with a solid basis, then receiving a terminal alkyne treatment. In organic synthesis, this reaction is useful for introducing alkynes into complicated compounds.Alkynes are an all-around adaptable class of molecules in organic chemistry, having a wide range of reactions and uses in synthesis, materials research, and business. Because of their special qualities, like acidity and reactivity, they are useful building blocks for the synthesis of intricate organic compounds.

Alkynes, when paired with alkynols, offer unique chemical properties in various applications. Retinol, a form of vitamin A, is widely used in skincare products for its anti-aging and skin-repairing benefits.
