Chiral is the chemistry term we use to describe objects whose mirror image is different from the original. 

  • The mirror image of any chiral molecule is called an enantiomer.
  • If a molecule has an internal line of symmetry, it will have the same mirror image (achiral).

Concept #1: What is chirality?

Draw the mirror image of the following molecule.

Example #1: Draw the mirror images of the following molecule. Determine if the mirror image is the same or different. If there is an internal line of symmetry, use a dotted line to indicate it on the original molecule.

Draw the mirror image of the following molecule.

Example #2: Draw the mirror images of the following molecules. Determine if the mirror image is the same or different. If there is an internal line of symmetry, use a dotted line to indicate it on the original molecule.
