cyclopentane

[¦sī·klō′pen‚tān]
(organic chemistry)
C5H10 A cyclic hydrocarbon that is a colorless liquid; present in crude petroleum, it is converted during refining to aromatics which improve antiknock and combustion properties of gasoline.

Cyclopentane

 

(also pentamethylene), a saturated alicyclic hydrocarbon having the structural formula

Cyclopentane is one of the simplest cycloalkanes. A colorless liquid with a characteristic odor, it has a boiling point of 49.3°C, a melting point of –93.9°C, and a density of 0.745 g/cm3 at 20°C. Cyclopentane is insoluble in water, but it is miscible with benzene, ether, and acetone. It is a component of petroleums.

Using Fischer-Hirschfelder-Taylor space filling models (Fischer) of the 2-(2-pyridyl) cyclopentanone and the 2-(2-pyridyl) cyclohexanone, the cycloalkane ring is rigid in both the enol and the keto form but steric interactions appear greater in the keto form of the cyclopentane ring and in the enol form of the cyclohexane ring thus favoring the enol form in the five membered ring and the keto form for the six membered ring.
