Identify Saturated Organic Compound

A saturated organic compound contains only single bonds between carbon atoms in its carbon chain. Unsaturated compounds contain one or more double or triple carbon-carbon bonds.

Understanding Chemical Nomenclature

• The suffix '-ene' indicates a double bond (unsaturated). Example: Propene.
• The suffix '-yne' indicates a triple bond (unsaturated). Example: Propyne.
• The suffix '-ane' indicates only single bonds (saturated). Example: Propane.

Analyzing the Options

• 2-Bromopropene: The '-ene' suffix indicates a carbon-carbon double bond. This is unsaturated.
• Propene: The '-ene' suffix indicates a carbon-carbon double bond. This is unsaturated.
• Propyne: The '-yne' suffix indicates a carbon-carbon triple bond. This is unsaturated.
• Bromopropane: The '-ane' suffix indicates that the carbon chain (propane) has only single bonds. The presence of bromine does not change the saturation of the carbon backbone. This is saturated.

Conclusion

Based on the nomenclature, Bromopropane is the only compound listed that has a saturated carbon backbone.
