Understanding Saturated Hydrocarbons
Saturated hydrocarbons are organic compounds consisting entirely of hydrogen and carbon, featuring only single bonds between the carbon atoms. This structure leads to the maximum number of hydrogen atoms attached to the carbon skeleton.
Identification of the Options
- Cyclohexane
- Cyclohexane is a saturated hydrocarbon (C6H12) with a ring structure and only single bonds.
- Butane
- Butane (C4H10) is a straight-chain saturated hydrocarbon, containing only single bonds.
- Isobutane
- Isobutane (C4H10) is a branched form of butane, also saturated with only single bonds.
- Benzene
- Benzene (C6H6) is an aromatic compound and is not a saturated hydrocarbon. It contains alternating double bonds, which means it does not have the maximum number of hydrogen atoms.
Conclusion
Thus, the correct answer is option 'D', Benzene, as it does not meet the criteria for a saturated hydrocarbon due to the presence of double bonds in its structure. Understanding the nature of these bonds is crucial in distinguishing between saturated and unsaturated hydrocarbons.
