Symmetry and Optical Activity: Do Your Molecules Have It?
Symmetry and optical activity are intricately linked in organic molecules. A molecule is optically active if it can rotate the plane of polarized light. Optical activity arises from the molecule’s lack of symmetry—specifically, its...

Conditions for Optical Activity: When Molecules Twist Light
For a molecule to exhibit optical activity, it must be chiral, meaning it has no internal plane of symmetry. Additionally, the solution or compound should not contain equal amounts of enantiomers (racemic mixture), as these cancel out...
