What is a plane of symmetry?
A:
A plane of symmetry is a mirror plane that divides a molecule into two identical halves, where one half is the reflection of the other.
Do achiral molecules usually have a plane of symmetry?
A: Yes, achiral molecules typically contain a plane of symmetry.
Can chiral molecules have a plane of symmetry?
A: No, chiral molecules do not have a plane of symmetry.
Why is CH₂BrCl considered achiral?
A: CH₂BrCl is achiral because it has a plane of symmetry that divides the molecule into two identical halves.
Why is CHBrClF considered chiral?
A: CHBrClF is chiral because it lacks a plane of symmetry and its mirror images are nonsuperimposable.
What structural feature ensures a molecule is chiral?
A: The absence of a plane of symmetry and the presence of a stereogenic center ensure chirality.
