Introduction Optical isomers , or enantiomers, have the same sequence of atoms and bonds but are different in their 3D shape. 2016-02-19 2018-05-23 Optical activity is the ability of a chiral molecule to rotate the plane of plane-polairsed light, measured using a polarimeter. A simple polarimeter consists of a … This phenomenon is known as optical activity, and compounds that rotate the plane of polarized light are said to be optically active. Figure 4 demonstrates how two pieces of polarizing material may be used to measure the specific rotation of an optically active compound with a device known as a polarimeter.

Se hela listan på byjus.com Chad breaks down the Optical Activity and the relationship between Specific and Observed Rotation, Optical Purity, and Enantiomeric Excess. I understood the simplified reason for optical activity of a compound based on the difference in the angular velocities of counter-rotating circularly polarized light. The difference is due to the spatial arrangement of different groups with different electronic configurations.

Meso Compunds Fischer projection Just like how your left foot doesn't quite fit your right shoe, molecules also can have properties that depend on their handedness! This property is called chirality. We will go over what makes a molecule chiral, stereoisomers, assigning configurations using the R,S system, optical activity and Fischer projections. Optical activity: Optical activity is the property of certain organic substances to rotate the plane of plane polarised light towards the right (clockwise) or towards the left (anticlockwise).
