Answer true or false. Cis- and trans -cycloalkanes have the same molecular formula but a different connectivity of their atoms. A cis isomer of a cycloalkane can be converted to its trans isomer by rotation about an appropriate carbon-carbon single bond. A cis isomer of a cycloalkane can be converted to its trans isomer by exchange of two groups at a stereocenter in the cis-cycloalkane. Configuration refers to the arrangement in space of the atoms or groups of atoms at a stereocenter. Cis- 1,4-dimethylcyclohexane and trans-1,4- dimethylcyclohexane are classified as conformations.
