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.

What are the only types of alkynes which can form acetylides?
Terminal alkynes can form acetylides.
How can you obtain cis and trans alkene from alkynes?
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.
Is Hydrogenation is used to convert alkenes and alkynes to alkanes?
True
Is an alkane polar or nonpolar?
Alkynes are polar, slightly more than alkanes or alkenes, due to electron density at their triple bond. However, liquid alkynes are non-polar solvents.
What are the examples of alkynes?
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.

What are the only types of alkynes which can form acetylides?
Terminal alkynes can form acetylides.
What are the double and triple bonded hydrocarbons called?
double bonded hydrocarbons are called "alkenes" and triple bonded hydrocarbons are called "alkynes"
What Compounds that contain only carbon and hydrogen are .?
They can be alkanes,alkenes and alkynes. They are commonly called hydrocarbons.
When is a hydrocarbon molecule classified as an alkyne?
Actually all hydrocarbons are not alkynes, but all alkynes are hydrocarbons. Alkynes contain carbon and hydrogen and hence they are known as hydrocarbons.
What are compounds that contain only carbon and hydrogen atoms?
Many compounds are composed of only carbon and hydrogen. These are the core of the group called hydrocarbons. They include compounds such as:methaneoctanepentanebenzenetoluenexylene
Another word for aliphatic?
Alkanes, alkenes, alkynes...
What is the term for an unsaturated hydrocarbon?
These compounds are alkenes and alkynes.
Do all alkynes have at least one cc double bond?
No, all alkynes have at least one Carbon-Carbon TRIPLE bond. Alkenes have one double bond.
How can you obtain cis and trans alkene from alkynes?
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.
What has the author James Alexander Pincock written?
James Alexander Pincock has written: 'The bromination of acetylenes' -- subject(s): Acetylene, Bromination
What are the pharmaceutical application of alkynes?
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.
