Cyclopropanes are a type of organic compound characterized by a three-membered carbon ring. This unique structure makes them one of the simplest cyclic alkanes. The three carbon atoms are bonded to each other, forming a triangle, and each carbon is also bonded to two hydrogen atoms. Due to their ring strain, cyclopropanes are more reactive than larger cyclic compounds. They can undergo various chemical reactions, including ring-opening reactions, which can lead to the formation of more stable compounds. Their distinct properties make them interesting in both synthetic chemistry and industrial applications.
