Conditions for Optical Activity: When Molecules Twist Light

9th - Higher Ed
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...

Optical Activity: When Light Meets Molecules

9th - Higher Ed
Optical activity refers to the ability of chiral compounds to rotate the plane of polarized light. Compounds that rotate light clockwise are termed dextrorotatory (+), while those that rotate it counterclockwise are levorotatory (−). The...
