How are propyne and ethyne similar?
both are examples of alkynes and hence have similar chemical properties.
What are the only types of alkynes which can form acetylides?
Terminal alkynes can form acetylides.
Why alkynes are called acetylenes?
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.

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

What are the only types of alkynes which can form acetylides?
Terminal alkynes can form acetylides.
What class of hydrocarbons contains at least one carbon-carbon triple bond?
The alkynes CnH2n-2 (with n= 2, 3, 4, etc.)Examples: ethyn C2H2, propyn C3H4
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 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.
What are held together by multiple covalent bonds?
Examples are oxygen, nitrogen , alkenes with carbon carbon double bonds, alkynes with carbon carbon triple bonds, the carbon oxygen double bonds in carbon dioxide
