Alkynes
Alkynes
Alkynes (pronounced: al-kynes) are a type of Hydrocarbon that contain a triple bond between two carbon atoms. The term "alkyne" is derived from the Greek word "alky" meaning "fat" and the suffix "-yne" which is used in organic chemistry to denote the presence of a triple bond.
Structure
Alkynes have the general formula CnH2n-2. The simplest alkyne, Ethyne, also known as acetylene, has the formula C2H2. In alkynes, the carbon atoms are sp hybridized and they form a linear structure. The triple bond in alkynes consists of one sigma bond and two pi bonds.
Properties
Alkynes are unsaturated hydrocarbons. They are generally more reactive than Alkenes due to the presence of two pi bonds. Alkynes undergo addition reactions, which are typical for unsaturated compounds. They can also undergo Hydrogenation, Halogenation, and Hydration reactions.
Uses
Alkynes have various applications in the chemical industry. They are used in the synthesis of a variety of chemical compounds, including polymers, dyes, and pharmaceuticals. Ethyne, in particular, is used in welding and cutting metals due to its high flame temperature when combined with oxygen.
