Ethane is an alkane and is relatively unreactive due to its single C-C and C-H bonds. It primarily undergoes reactions like combustion and free radical halogenation, but it does not readily participate in addition reactions.
Ethene is an alkene and is more reactive than ethane. It contains a carbon-carbon double bond, which makes it susceptible to addition reactions. Ethene can react with halogens, hydrogen, and other reagents, making it more reactive than ethane and benzene.
Benzene is an aromatic compound with a stable, cyclic structure and delocalized π-electrons. This delocalization gives benzene significant stability, making it less reactive than alkenes and alkynes.
Ethyne, or acetylene, is an alkyne and is more reactive than ethane and benzene. It contains a carbon-carbon triple bond, which is highly reactive. Alkynes can participate in a variety of addition reactions and can react with a range of reagents, making them among the more reactive hydrocarbons.
Ethane is an alkane and is relatively unreactive due to its single C-C and C-H bonds. It primarily undergoes reactions like combustion and free radical halogenation, but it does not readily participate in addition reactions.
