Detailed explanation-1: -Alkynes are hydrocarbons which contain carbon-carbon triple bonds. Their general formula is CnH2n-2 for molecules with one triple bond (and no rings). Alkynes undergo many of the same reactions as alkenes, but can react twice because of the presence of the two p-bonds in the triple bond.

Detailed explanation-2: -An alkyne is a hydrocarbon containing triple bonds. The general formula of an alkyne is CnH2n-2.

Detailed explanation-3: -Alkynes. Hydrocarbon molecules with one or more triple bonds are called alkynes; they make up another series of unsaturated hydrocarbons. Two carbon atoms joined by a triple bond are bound together by one bond and two bonds.

Detailed explanation-4: -Higher alkenes and alkynes are named by counting the number of carbons in the longest continuous chain that includes the double or triple bond and appending an-ene (alkene) or-yne (alkyne) suffix to the stem name of the unbranched alkane having that number of carbons.

Detailed explanation-5: -There are three types of unsaturated hydrocarbons: alkenes, alkynes and aromatic hydrocarbons. Alkenes have one or more carbon-carbon double bond. Alkynes have one or more carbon-carbon triple bond, and aromatic hydrocarbons have a benzene or aromatic ring in their structure.
