WebCycloalkanes are alkanes joined in a closed loop to form a ring-shaped molecule, and they are named by using the alkane names above, with cyclo-as a prefix. These start with propane, or rather cyclopropane, which has the minimum number of carbon atoms to form a closed shape: three atoms, forming a triangle. WebSaturated hydrocarbons that contain one ring are referred to as cycloalkanes. With a general formula of C n H 2n ( n is an integer greater than 2), they have two fewer hydrogen atoms than an alkane with the same number of carbon atoms.
