Given the three molecules 1-methylcyclohexanol, trans-2-methylcyclohexanol, and trans-4-methylcyclohexanol, which of the following statements is true?
A) All three molecules are chiral.
B) Only 1-methylcyclohexanol and trans-2-methylcyclohexanol are chiral.
C) Only trans-2-methylcyclohexanol is chiral.
D) Only trans-2-methylcyclohexanol and trans-4-methylcyclohexanol are chiral.

Question

Quizplus · Accepted Answer

Only trans-2-methylcyclohexanol is chiral because it has four different groups attached to the carbon atom bearing the hydroxyl group, making it the only molecule among the options that lacks a plane of symmetry and thus is chiral. 1-methylcyclohexanol and trans-4-methylcyclohexanol are not chiral because they each have a plane of symmetry.
