Quizplus · Accepted Answer

Compound II (2-bromobutane) does not have a plane of symmetry because the molecule is chiral, meaning it cannot be superimposed on its mirror image. Compound I (2-chlorobutane) and IV (1,2-dichloropropane) have planes of symmetry, while III (1-chloropropane) has an improper plane of symmetry (also known as a plane of symmetry combined with a C2 rotation).
