In organic chemistry, the cycloalkanes (also called naphthenes, but distinct from naphthalene) are the monocyclic saturated hydrocarbons. [1] In other words, a cycloalkane consists only of hydrogen and carbon atoms arranged in a structure containing a single ring (possibly with side chains ), and all of the carbon-carbon bonds are single .
Because (1R,3R)-1,2,3-trimethylcyclopentane is a cycloalkane, its three methyl substituents are capable of exhibiting cis/trans isomerism. This implies that the methyl groups in positions 1,2, and 3 may occupy different spatial arrangements (i.e.they may either lay cis or trans with respect to each other).
Cycloalkenes have a lower melting point than cycloalkanes of the same size. The lowered melting point is due to the double bond preventing the compound from compact packing. Cycloalkenes generally reflect physical properties of their cycloalkane. In physical states, only the smaller cycloalkenes are gases while the others are mostly liquid.

Cyclopropane is the cycloalkane with the molecular formula (CH 2) 3, consisting of three methylene groups (CH 2) linked to each other to form a triangular ring.The small size of the ring creates substantial ring strain in the structure.
1,2-Dimethylcyclopropane is a cycloalkane consisting of a cyclopropane ring substituted with two methyl groups attached to adjacent carbon atoms. [1] It has three stereoisomers, one cis-isomer and a pair of trans-enantiomers, which differ depending on the orientation of the two methyl groups.
Cyclooctane is a cycloalkane with the molecular formula (CH 2) 8. [2] It is a simple colourless hydrocarbon, but it is often a reference compound for saturated eight-membered ring compounds in general. Cyclooctane has a camphoraceous odor. [3]
