Cyclopentane is a cyclic hydrocarbon with the molecular formula C5H10. It is a colorless, flammable liquid with a gasoline-like odor. Cyclopentane is an alicyclic compound, which means it contains a ring of carbon atoms in its structure. It is a simple five-membered ring, with each carbon atom bonded to two hydrogen atoms.
Cyclopentane is a non-polar molecule, which means it does not dissolve easily in water but dissolves well in nonpolar solvents. It is commonly used as a solvent, particularly in the production of polyurethane foam, and as a refrigerant. It is also used as a starting material in the synthesis of other chemicals, including pharmaceuticals and agrochemicals.
