Space-filling models of the cyclopropane molecule
, 2022 Cyclopropane is a cycloalkane, consisting of three methylene groups linked to each other to form a ring. The small size of the ring creates substantial ring strain in the structure. Cyclopropane itself is mainly of theoretical interest but many of its
