Unsaturated hydrocarbons with at least one triple bond are known as?
- Correct Answer: alkynes
- aromatic hydrocarbons
- benzenes
- alkenes
Explanation: Unsaturated hydrocarbons that contain at least one triple bond are called alkynes . The name of specific alkynes always end in – yne , with a prefix for the number of carbon atoms. Figure below shows the smallest alkyne, called ethyne, which has just two carbon atoms. Ethyne is also called acetylene. It is burned in acetylene torches, like the one in Figure below . Acetylene produces so much heat when it burns that it can melt metal. Breaking all those bonds between carbon atoms releases a lot of energy.
