Final answer:

Cyclooctene, which has a single double bond, does not exhibit cis, trans isomerism like cycloalkanes with substituents do. In cycloalkanes, cis and trans refer to the relative orientation of substituents around the ring. Cyclohexane, for example, has puckered conformations to minimize ring strain.

Step-by-step explanation:

The question 'Does Cyclooctene have 2 distinct configurations' explores the concept of cis, trans isomerism in cyclic compounds like cyclooctene. However, it's noteworthy that cyclooctene, which has a single double bond, does not exhibit this type of isomerism as cis-trans isomerism typically applies to situations where there are substituents on a cycloalkane or on a double bond in a noncyclic alkene.

In cycloalkanes, configurations are often referred to as cis or trans depending on the relative orientation of substituents. When the two substituents are on the same side of the molecule, it is the 'cis' isomer; if they are on opposite sides, it's the 'trans' isomer. As for cyclohexane, which is a saturated ring, the molecule is puckered into a chair conformation to reduce ring strain, making it not planar and allowing the bond angles to approximate the tetrahedral angle of 109.5°. Therefore, each substituent can adopt either an axial or equatorial position, leading to different conformations.

When considering molecules like trans-1,2-dimethylcyclopropane and cis-1,2-dimethylcyclopropane, these depict stereoisomerism in cycloalkanes, where the same formula can have isomers with different physical properties such as boiling points. Another aspect is the existence of diastereomers, which are not mirror images of each other but are still stereochemically different, such as in the case of 1,2-dimethylcyclopropane.
