"WebCyclopentane has very little angle strain (the angles of a pentagon are 108º), but its eclipsing strain would be large (about 10 kcal/mol) if it remained planar. Consequently, the five-membered ring adopts non-planar puckered conformations whenever possible. Rings larger than cyclopentane would have angle strain if they were planar. " - Ph of cyclopentane

Cyclopentane (also called C pentane) is a highly flammable alicyclic hydrocarbon with chemical formula C5H10 and CAS number 287-92-3, consisting of a ring of five carbon atoms each bonded with two hydrogen atoms above and below the plane. It occurs as a colorless liquid with a petrol-like odor. Its melting point is −94 °C and its boiling point is 49 °C. Cyclopentane is in the class of cycloalkanes, being alkanes that have one or more rings of carbon atoms. It is formed by cracking WebJun 22, 2024 · Description. Cyclopentane is used as green blowing agent and involved in the production of polyurethane insulating foam, which is used in refrigerators, freezers, water heaters, construction panels, insulated pipes and roofs. As a lubricant, it finds applications in computer hard drives and outer space equipment due to its low volatile nature.
