Enantiomers: Mirror Images in Organic Chemistry

Concept Map

Edit available

Enantiomers are chiral molecules in organic chemistry that are mirror images of each other but not superimposable. They share physical properties but differ in chemical behavior, especially in biological systems. Enantiomers' optical activity, R and S configurations, and their significance in pharmaceuticals, food, and perfumery industries are discussed. The text also explores the impact of enantiomers on drug safety and development, highlighting the importance of chirality in medicinal chemistry.

Understanding Enantiomers in Organic Chemistry

Enantiomers are a specific type of stereoisomer in organic chemistry, defined as molecules that are mirror images of each other but cannot be superimposed. These compounds have the same molecular and structural formulas; however, their atoms are arranged in a three-dimensional space in such a way that they are chiral, similar to how left and right hands are mirror images but not superimposable. Enantiomers are a category of isomers, which are molecules with the same molecular formula but different arrangements of atoms. Enantiomers are also known as optical isomers because they have the unique property of rotating plane-polarized light in opposite directions, a phenomenon referred to as optical activity.

Physical and Chemical Properties of Enantiomers

Enantiomers generally share identical physical properties, including melting points, boiling points, solubility, and densities. However, they often exhibit distinct chemical behaviors in chiral environments, such as when interacting with other chiral molecules, including biological macromolecules like proteins. One enantiomer may rotate plane-polarized light to the right, termed dextrorotatory, while the other may rotate it to the left, termed levorotatory. The degree of rotation, known as specific rotation, is calculated using a formula that takes into account the observed rotation, the length of the light path through the sample, and the sample concentration. These differences in behavior are crucial in biological contexts, where one enantiomer of a compound may be biologically active and the other inactive or even toxic.

Difference between enantiomers and diastereomers

Enantiomers are non-superimposable mirror images; diastereomers are stereoisomers that are not mirror images.

01

Chirality in molecules

Chirality refers to a molecule's property of having a non-superimposable mirror image, often due to an asymmetric carbon atom.

02

Role of chiral centers in enantiomers

Chiral centers, typically carbon atoms with four different substituents, create enantiomers by allowing for two non-superimposable configurations.
