WebApr 1, 2016 · Apr 1, 2016. Consider the following questions: Do you think two methylene bridges, −CH2 −, are different, if they are symmetrical when reflecting through a mirror plane that bisects the upper-right and bottom-left corners of the cyclohexane ring? Now that you know whether there is or isn't a mirror plane, do you still think it is chiral?

WebApr 6, 2024 · Chiral center means the carbon atom in the system that has all the different substituents. Complete step by step answer: Ring structures are those in which there is no straight chain, there is a closed system, and this closed system can have single bonds and multiple bonds. So, cyclohexane is a ring structure and it has only single bonds.
