Which of the following is an unsaturated hydrocarbon?
Ethane
Propane
Ethene
Butane
Ethene
Unsaturated hydrocarbons are organic compounds containing at least one carbon-carbon double or triple bond. Ethene, with the chemical formula C2тАЛH4тАЛ, contains a carbon-carbon double bond, making it an unsaturated hydrocarbon.
Unsaturated hydrocarbons are organic compounds containing at least one carbon-carbon double or triple bond. Ethene, with the chemical formula C2тАЛH4тАЛ, contains a carbon-carbon double bond, making it an unsaturated hydrocarbon.
Think of a saturated hydrocarbon like a bus where every seat is occupied by a passenger (hydrogen atom), while an unsaturated hydrocarbon has 'empty seats' (multiple bonds) that can be opened up to fit more passengers through a chemical reaction.
ANE-ENE-YNE: Saturated (single), Unsaturated (double), Unsaturated (triple).
CnтАЛH2n+2тАЛ тАФ General formula for Saturated Alkanes
CnтАЛH2nтАЛ тАФ General formula for Alkenes (Unsaturated)
CnтАЛH2nтИТ2тАЛ тАФ General formula for Alkynes (Unsaturated)
Hydrocarbons are classified based on the nature of their carbon-carbon bonds. Alkanes (CnтАЛH2n+2тАЛ) possess only single bonds (saturated). Alkenes (CnтАЛH2nтАЛ) possess at least one double bond and alkynes (CnтАЛH2nтИТ2тАЛ) possess at least one triple bond, both being unsaturated as they can undergo addition reactions.
Unsaturated hydrocarbons undergo addition reactions due to the presence of ╧А-bonds.
Alkenes and alkynes are the two primary classes of unsaturated hydrocarbons.
Ethene is the simplest alkene with the structure CH2тАЛ=CH2тАЛ.
Unsaturated hydrocarbons are highly reactive due to the electron-rich double/triple bonds, making them crucial building blocks in industrial polymer synthesis.
Ethene is widely used in the production of polyethylene plastic.
Unsaturated fats (oils) are essential in dietary biology.
Ethane (C2тАЛH6тАЛ), Propane (C3тАЛH8тАЛ), and Butane (C4тАЛH10тАЛ) are all alkanes and follow the general formula CnтАЛH2n+2тАЛ, which defines them as saturated hydrocarbons.
Degree of unsaturation is a key parameter used to identify the number of rings or multiple bonds in a molecule.
C is correct тАФ Ethene is an unsaturated hydrocarbon because it contains a carbon-carbon double bond.
Always check the suffix of the name: '-ane' implies saturated, while '-ene' or '-yne' indicates unsaturation.
