trans-1,2-Dibromocyclohexane is represented by structure(s):

Question

Quizplus · Accepted Answer

The structure of trans-1,2-Dibromocyclohexane has two bromine atoms attached at the 1 and 2 positions of the cyclohexane ring in a trans configuration. 
Structure I has both bromine atoms on the same side of the ring, making it cis instead of trans, so it cannot be the correct representation of trans-1,2-Dibromocyclohexane. 
Structure II and III both have the bromine atoms in a trans configuration, so they are both possible representations. Therefore, the best choice is D, which includes both options.
