cyclopentane

Pentagonal hydrocarbon molecule

Cyclopentane is a hydrocarbon molecule consisting of five carbon atoms arranged in a ring, each bonded to two hydrogen atoms.

It's a colorless liquid used as a blowing agent in foam insulation and as a solvent.

The cyclo- prefix indicates the ring structure that distinguishes it from straight-chain pentane.
