Chemistry - STEREO ISOMERISM Question with Solution | TestHub

Ans. (D) trans-1-ethyl-3-methylcyclohexane.

Sol. Only a chiral compound can be resolved into enantiomers. cis-1,2-Dimethylcyclohexane is meso (plane of symmetry), and 1,1- and trans-1,4-dimethylcyclohexane each have an internal plane and no stereocentre. In trans-1-ethyl-3-methylcyclohexane the two ring stereocentres bear different groups, so no symmetry element remains; the compound is chiral and resolvable.
