What is the Difference Between Cyclopentane and Cyclopentene?
🆚 Go to Comparative Table 🆚Cyclopentane and cyclopentene are both cyclic hydrocarbons, but they have different structures and properties. The key difference between them is:
- Saturation: Cyclopentane is a saturated hydrocarbon, meaning it has only single bonds between carbon atoms, whereas cyclopentene is an unsaturated hydrocarbon, containing a double bond between two carbon atoms.
- Chemical Formula: Cyclopentane has the chemical formula C5H10, while cyclopentene has the chemical formula C5H8.
- Reactivity: Cyclopentene, being an unsaturated compound, reacts with bromine water, turning it from orange to colorless due to the addition of bromine to the double bond. In contrast, cyclopentane, being a saturated compound, does not react with bromine water, and the orange color remains unchanged.
- Stability: Cyclopentane is more stable than cyclopentene due to the absence of a reactive double bond.
In summary, cyclopentane and cyclopentene differ in their saturation, chemical formula, reactivity, and stability. Cyclopentane is a saturated cyclic hydrocarbon, while cyclopentene is an unsaturated one containing a double bond.
Comparative Table: Cyclopentane vs Cyclopentene
The main difference between cyclopentane and cyclopentene lies in their saturation state. Here is a table comparing the two compounds:
Property | Cyclopentane | Cyclopentene |
---|---|---|
Saturation | Saturated (no double or triple bonds) | Unsaturated (has double bonds) |
Chemical Formula | C5H10 | C5H8 |
Molar Mass | 70.1 g/mol | 68.11 g/mol |
Melting Point | -93.9 °C | -135 °C |
Boiling Point | 49.2 °C | 45 °C |
Production Method | Cracking cyclohexane using alumina as a catalyst | Steam cracking of naphtha |
Cyclopentane is an alicyclic hydrocarbon with a saturated ring structure, while cyclopentene has an unsaturated ring structure with double bonds. Cyclopentane has a higher molar mass and boiling point compared to cyclopentene, and it is produced by cracking cyclohexane using alumina as a catalyst. Cyclopentene, on the other hand, is produced on an industrial scale via steam cracking of naphtha.
