Among the dimethylcyclohexanes, which one can be obtained in enantiopure form?
(a)
(b)
(c)
(d)
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
trans-1,2-Dimethylcyclohexane (a) has no mirror plane and is chiral, so it can be obtained enantiopure. The cis-1,2 isomer interconverts with its mirror image by ring flip, and the 1,3 and 1,4 isomers drawn are achiral.
