Because chiral molecules are able to rotate the plane of polarization differently by interacting with the electric field differently, they are said to be optically active. In general molecules that rotate light in differen directions are called optical isomers.
How do you know if a molecule is optically active?
The compounds which are capable of optical rotation are said to be optically active compounds. All the chiral compounds are optically active. The chiral compound contains an asymmetric center where the carbon is attached with four different atoms or groups. It forms two non-superimposable mirror images.
What makes a molecule optically active?
A chiral molecule that rotates light is said to be optically active. If the molecule rotates the plane-polarized light in the clockwise direction, we call that rotation a dextrorotatory rotation. However, if the light rotates counterclockwise, we call that rotation levorotatory.
