Question

Quizplus · Accepted Answer

The correct IUPAC name for the compound described in option C would not use the prefix "cis-" because "cis-" is used to describe the relative configuration of substituents on a double bond or in a cyclic compound when there are only two substituents. In the case of "1,1,2-trimethylcyclohexane," the use of "cis-" is inappropriate because the description does not involve a comparison of substituents across a double bond or around a ring in a way that "cis-" would be meaningful. The correct naming would simply list the substituents without using "cis-".
