The general molécular formula of alkynes is

Key Points

• The general molecular formula for alkynes is Cn H2n - 2
• Alkynes are hydrocarbons that contain at least one carbon-carbon triple bond.
• This triple bond gives alkynes distinct properties compared to alkanes and alkenes.
• Alkynes are unsaturated hydrocarbons, meaning they have fewer hydrogen atoms than alkanes.
• The simplest alkyne is ethyne, also known as acetylene, with the formula C2 H2

Additional Information

• Alkynes are more reactive than alkanes due to the presence of the triple bond.
• They are used in various industrial applications, including welding and the synthesis of organic compounds.
• Alkynes can undergo a variety of chemical reactions, such as hydrogenation, halogenation, and polymerization.
