Question
Which of the following statements is not true regarding pairs of enantiomers? ans. They have identical boiling points
They have identical melting points
They react at identical rates with chiral reagents
They rotate plane polarized light in opposite directions
Solution
The statement that is not true regarding pairs of enantiomers is: "They react at identical rates with chiral reagents."
Enantiomers are non-superimposable mirror images and have identical physical properties such as boiling points and melting points. They also rotate plane polarized light in opposite directions. However, they do not react at identical rates with chiral reagents. This is because chiral reagents can distinguish between enantiomers, leading to different reaction rates. This property is used in chiral resolution, the process of separating enantiomers.
