Answer :
Final answer:
Cis-trans isomers of cycloalkanes have a different arrangement of atoms and different physical properties.
Explanation:
Cis-trans isomerism refers to the different configurations of compounds that have a rigid structure in their molecule, such as alkenes and cyclic compounds. In the case of cycloalkanes, cis-trans isomers have two characteristics. Firstly, they have a different arrangement of atoms, where two alkyl groups can either point in the same direction (cis orientation) or in opposite directions (trans orientation). Secondly, they have different physical properties, such as boiling points, due to their different structural formulas.
