Which of the following statements about enantiomers is true?
  1. They have identical physical properties.
  2. They rotate plane-polarized light in opposite directions.
  3. They can be separated by simple distillation.
  4. They have the same molecular formula but different connectivity.

Questions & Step-by-Step Solutions

Which of the following statements about enantiomers is true?
  • Step 1: Understand what enantiomers are. They are a type of stereoisomer that are mirror images of each other.
  • Step 2: Recognize that enantiomers cannot be superimposed. This means you cannot place one on top of the other and have them match perfectly.
  • Step 3: Learn about plane-polarized light. This is light that vibrates in a single plane.
  • Step 4: Know that enantiomers affect plane-polarized light differently. One enantiomer will rotate the light in one direction (clockwise), while the other will rotate it in the opposite direction (counterclockwise).
  • Step 5: Conclude that the statement about enantiomers being non-superimposable mirror images and rotating plane-polarized light in opposite directions is true.
