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 differences between internal alkynes and terminal alkynes in terms of their chemical properties and reactivity?
Internal alkynes have alkynes in the middle of a carbon chain, while terminal alkynes have alkynes at the end of a carbon chain. In terms of chemical properties and reactivity, internal alkynes are less reactive than terminal alkynes due to the presence of more stable carbon-carbon bonds in the chain. Terminal alkynes are more reactive and undergo addition reactions more readily than internal alkynes.
What are the only types of alkynes which can form acetylides?
Terminal alkynes, which have a triple bond at the end of the carbon chain, are the only types of alkynes that can form acetylides. Internal alkynes, which have a triple bond between two carbon atoms in the middle of the carbon chain, do not readily form acetylides.
What is the general name of a hydrocarbons with at least one triple covalent bond?
Alkynes
How are propyne and ethyne similar?
Propyne and ethyne are both alkynes, which means they contain a carbon-carbon triple bond. They are both colorless gases at room temperature and have similar chemical reactivities due to the presence of the triple bond.
What are the differences between internal and terminal alkynes in terms of their chemical properties and reactivity?
Internal alkynes have a triple bond between carbon atoms within the molecule, while terminal alkynes have a triple bond at the end of the carbon chain. Terminal alkynes are more reactive due to the presence of a hydrogen atom on the terminal carbon, making them more susceptible to nucleophilic attack. Internal alkynes are less reactive and more stable due to the lack of a hydrogen atom on the internal carbon.
What are the differences between internal alkynes and terminal alkynes in terms of their chemical properties and reactivity?
Internal alkynes have alkynes in the middle of a carbon chain, while terminal alkynes have alkynes at the end of a carbon chain.

Terminal alkynes, which have a triple bond at the end of the carbon chain, are the only types of alkynes that can form acetylides. Internal alkynes, which have a triple bond between two carbon atoms in the middle of the carbon chain, do not readily form acetylides.
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 is the general name of a hydrocarbons with at least one triple covalent bond?
Alkynes
Write the formula of unsaturated hydrocarbon.?
The general formula for unsaturated hydrocarbons is CnH2n. Examples include alkenes and alkynes.
How are propyne and ethyne similar?
Propyne and ethyne are both alkynes, which means they contain a carbon-carbon triple bond. They are both colorless gases at room temperature and have similar chemical reactivities due to the presence of the triple bond.
What class of hydrocarbons contains at least one carbon-carbon triple bond?
Alkynes are hydrocarbons that contain at least one carbon-carbon triple bond. They are unsaturated hydrocarbons and are known for their characteristic triple bond, giving them distinct chemical properties compared to alkanes and alkenes.
What are the differences between internal and terminal alkynes in terms of their chemical properties and reactivity?
Internal alkynes have a triple bond between carbon atoms within the molecule, while terminal alkynes have a triple bond at the end of the carbon chain. Terminal alkynes are more reactive due to the presence of a hydrogen atom on the terminal carbon, making them more susceptible to nucleophilic attack. Internal alkynes are less reactive and more stable due to the lack of a hydrogen atom on the internal carbon.
What is the difference in acidity between alkynes, alkenes, and alkanes?
Alkynes are more acidic than alkenes and alkanes. Alkenes are more acidic than alkanes.
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
The general name for hydrocarbons with at least one triple covalent bond is?
The general name for hydrocarbons with at least one triple covalent bond is alkynes.
What is the general formula of alkynes?
The general formula of alkynes is CnH2n-2, where "n" represents the number of carbon atoms in the alkyne molecule. Alkynes are hydrocarbons that contain at least one carbon-carbon triple bond.
