Quizplus · Accepted Answer

Compound II is the only chiral compound, as it has a carbon atom with four different substituents. Compound I is achiral because it has a plane of symmetry that divides the molecule into two equal halves. Compound III is also achiral because it has a mirror plane of symmetry perpendicular to the page that divides the molecule into two equal halves. Thus, the correct answer choice is B, which represents only Compound II being chiral.
