Alkynes
Alkynes are also
unsaturated hydrocarbons. The number of hydrogen atoms is still less in alkynes
as compared to alkenes or alkanes. Their general formula is CnH2n–2.
The first stable member of alkyne series is ethyne which
is popularly known as acetylene. Alkynes are starting materials for a large
number of organic compounds.
