Olefiant gas belongs to which of the following functional groups?
Ketone
Alkynes
Alkenes
Halo alkane
Alkenes
Olefiant gas is the historical name for ethylene (C2тАЛH4тАЛ), which is the simplest member of the alkene homologous series. It belongs to the alkene functional group characterized by a carbon-carbon double bond.

Think of the alkene double bond as a 'handshake' that is ready to let go of one hand to grab onto two new things (addition), which is exactly how ethylene behaves when it 'oils' up by reacting with halogens.

CH2тАЛ=CH2тАЛ тАФ Structural representation of ethylene (Olefiant gas)
The term 'Olefiant' is derived from the Latin 'oleum' (oil) and 'facere' (to make), signifying that ethylene forms oily liquids upon reaction with chlorine or bromine. This addition reaction is a diagnostic test for alkenes, where the double bond breaks to incorporate halogens, resulting in the formation of dihaloalkanes.
Ethylene is the first member of the alkene series.
It contains a sp2 hybridized carbon atom involved in a ╧А-bond.
It is a ripening agent for fruits in agriculture.
Important monomer for the production of polyethylene.
Essential chemical intermediate in organic synthesis.
Highly flammable gas.
Can act as an asphyxiant in high concentrations.
Manufacture of plastics like polyethylene.
Controlled ripening of fruits like bananas and tomatoes.
Olefiant gas was first discovered by Dutch chemists in 1795.
Option A is incorrect because ketones contain a carbonyl group (C=O).
Option B is incorrect because alkynes contain carbon-carbon triple bonds (CтЙбC).
Option D is incorrect because haloalkanes contain a halogen atom bonded to an sp3 hybridized carbon.
C is correct тАФ Olefiant gas is the archaic name for ethylene, which is an alkene with the formula C2тАЛH4тАЛ.
Remember that 'Olefin' is a synonym for 'Alkene'; if you see it in a question, immediately associate it with the CnтАЛH2nтАЛ general formula.
