Alkynes are the organic molecule that contains triple bonds between the carbon atoms. Its general formula is CnH2n-2. They are also known as acetylenes. In this article, we will deal with the structure of alkynes. Alkynes are the most common term studied by the students in general organic chemistry.

Triple bond in alkynes shows the following features:
Answer: Five properties of alkynes are given below:
Alkynes are non-polar, unsaturated hydrocarbons.
Alkynes are highly soluble in organic and non-polar solvents and slightly soluble in polar solvents.
Compared to other hydrocarbons like alkanes and alkenes, alkynes have a high boiling point.
Alkynes in a reaction release a high amount of energy due to the repulsion of electrons.
Alkynes are more acidic than alkanes and alkenes due to SP hybridisation.
Question 2: Explain the Bond Structure of Alkynes.
Answer: In alkynes, a triple bond exists between carbon. The hybridization of triple bonded carbon in alkyne is SP. Bond angle between the two SP hybridised carbon is 180 degrees. The bond length of the triple bond in alkynes is 121 picometer.
