Which of the following organic compounds is synonymous with olefiant gas which is used to make anaesthetics, refrigerants and other chemicals?

The correct answer is Ethylene.

Key Points

• Ethylene, also known as the ripening hormone plays a role in plant growth.
• Ethylene appears as a colorless gas with a sweet odor and taste.
• It is lighter than air.
• Ethylene is used in used to make anaesthetics, refrigerants and other chemicals.
• It is also an important natural plant hormone and is used in agriculture to force the ripening of fruits.
• The hydrate of ethylene is ethanol.

Additional InformationMethane

• This compound contains 1 carbon atom which is indicated by writing 'meth'.
• This compound has all single bonds, so it is saturated.
• The saturated hydrocarbon is indicated by the ending 'ane'.
• On joining 'meth' and 'ane', the IUPAC name of its compound becomes,' 'methane'.
• The molecular formula of methane is CH4.
• Thus, the IUPAC name as well as the common name of the hydrocarbon CH4 is the same, methane. 
• It is an Alkane and its general formula is CnH2n+2.

​Butane

• Butane is one of two saturated hydrocarbons, or alkanes, with the chemical formula C4H10 of the paraffin series. In both compounds, the carbon atoms are joined in an open chain. In n-butane the chain.
• Butane derivatives are highly flammable, colorless, easily liquefied gases that quickly vaporize at room temperature.
• IUPAC Nomenclature of Butane is (CH3CH2CH2CH3).
• Butane is added to the gasoline and increases its volatility in cold climates. Transformed to isobutane in a refinery process known as isomerization, it can be reacted with certain other hydrocarbon derivatives such as butane to form valuable high-octane constituents of gasoline.
