CYCLOPENTANE in planar conformation has no angle strain, but suffers from the eclipsing strain.

Alkylated CYCLOPENTANE (MAC) lubricants have low volatility and are used in some specialty applications
CYCLOPENTANE occurs as a colorless liquid with a petrol-like odor.

Meanwhile, in the absence of oxygen, CYCLOPENTANE will undergo a pyrolysis reaction that decomposes into smaller and unsaturated molecules.
On the other hand, CYCLOPENTANE can react with bromine under ultraviolet radiation.
