ALKYNES
Alkynes are hydrocarbons with at least one carbon-carbon triple bond (C≡C) in their structure, following the general formula CnH2n-2. They are unsaturated compounds, meaning they have fewer hydrogen atoms than alkanes or alkenes. Examples include ethyne (C2H2), commonly known as acetylene. Alkynes undergo addition reactions, such as hydrogenation (adding hydrogen) and halogenation (adding halogens), and are used in organic synthesis and as fuel in welding. Their triple bond makes them highly reactive compared to alkanes and alkenes. Let me know if you need further clarification or examples!
