Quizplus · Accepted Answer

Compound I is not chiral because it has a plane of symmetry. Compound II is chiral because it has four different substituents on its stereocenter. Compound III is not chiral because it has a dihedral plane of symmetry. Compound IV is chiral because it has four different substituents on its stereocenter. Therefore, only II and III are chiral compounds.
