Saturated Hydrocarbons Definition
Saturated hydrocarbons are organic compounds consisting only of hydrogen and carbon atoms, where all the carbon-carbon bonds are single bonds. This means they contain the maximum possible number of hydrogen atoms for a given number of carbon atoms.
Understanding Hydrocarbon Types
- Alkanes: These are hydrocarbons where all carbon-carbon bonds are single bonds (C-C). They fit the definition of saturated hydrocarbons. Example: Ethane ($C_2H_6$).
- Alkenes: These contain at least one carbon-carbon double bond (C=C). They are unsaturated because they have fewer hydrogen atoms than the corresponding alkane. Example: Ethene ($C_2H_4$).
- Alkynes: These contain at least one carbon-carbon triple bond (C≡C). They are also unsaturated. Example: Ethyne ($C_2H_2$).
- Isomers: Compounds with the same molecular formula but different structural arrangements. This term describes structural relationships, not the saturation level itself.
Conclusion
Based on the definition, hydrocarbons containing only single carbon-carbon bonds are classified as saturated hydrocarbons. Among the given options, only alkanes fit this description.
