Physical and chemical properties of alicyclic hydrocarbons

Cyclopropane and cyclobutane are gases remaining alicyclic compound are liquid or solid substance. Cycloalkanes have boiling at 10-20 ° C higher, and a density 20% greater than the corresponding n-alkanes. For strained alicyclic compounds with small and medium cycles characteristic abnormally high heat of combustion.
In general, the physical properties of cycloalkanes largely resemble saturated acyclic hydrocarbons.
