Alkynes are a similar functional group to alkanes and alkenes.
The difference is that alkynes have a triple bond between two carbon atoms.
The most well known alkyne is Ethyne (Acetylene) .
Its structure is H-C///C-H . This gas is used in oxy-acetylene burners, and produces a very hot flame to melt metals.
Other alkynes are
Propyne ; H-C///C-CH3
But-1-yne ; H-C///C - CH2-CH3
But-2-yne ; H3C-C///C-CH3
Be careful when spellings these chemcial names , there is only ONE letter difference. alkAne, alkEne, & alkYne.
examples of alkynes
both are examples of alkynes and hence have similar chemical properties.
Terminal alkynes can form acetylides.
alkynes are those hydrocabons wich have triple co alent bond among carbon atoms . The first member of alkyne series is known as acetylene.This is the sim;lest alkyne ,with molecular formula( C2H2).Alkynes are also called acetylenes because of the name of the first member of the series is actylene.

Add bulky groups on alkynes as iodination of alkynes which always give trans di-iodo products then substitution of iodine atoms with other groups produce other trans products for cis alkenes simply perform the controlled hydrogenation.
Examples are oxygen, nitrogen , alkenes with carbon carbon double bonds, alkynes with carbon carbon triple bonds, the carbon oxygen double bonds in carbon dioxide
both are examples of alkynes and hence have similar chemical properties.
Terminal alkynes can form acetylides.
The alkynes CnH2n-2 (with n= 2, 3, 4, etc.)Examples: ethyn C2H2, propyn C3H4
Actually all hydrocarbons are not alkynes, but all alkynes are hydrocarbons. Alkynes contain carbon and hydrogen and hence they are known as hydrocarbons.
Many compounds are composed of only carbon and hydrogen. These are the core of the group called hydrocarbons. They include compounds such as:methaneoctanepentanebenzenetoluenexylene

Alkanes, alkenes, alkynes...
These compounds are alkenes and alkynes.
No, all alkynes have at least one Carbon-Carbon TRIPLE bond. Alkenes have one double bond.
Add bulky groups on alkynes as iodination of alkynes which always give trans di-iodo products then substitution of iodine atoms with other groups produce other trans products for cis alkenes simply perform the controlled hydrogenation.
Alkynes are present in efavirenz, an HIV/AIDS treatment and preventative sold as Sustiva and other names, as well as the antifungal medication terbinafine (sold as Lamisil). Alkynes are also present in aggressive anti-tumor drugs. They used to be present in the contraceptive noretynodrel, which is no longer marketed.
Examples are oxygen, nitrogen , alkenes with carbon carbon double bonds, alkynes with carbon carbon triple bonds, the carbon oxygen double bonds in carbon dioxide
