FAQs on Optical activity-Dextrorotatory- laevorotatory-Angle of rotation & specific rotation Video Lecture - Crash Course for IIT JAM Chemistry

1. What is optical activity?
Ans. Optical activity refers to the ability of certain substances to rotate the plane of polarized light. This rotation occurs due to the asymmetry in the molecular structure of the substance.
2. What is the difference between dextrorotatory and laevorotatory?
Ans. Dextrorotatory and laevorotatory are terms used to describe the direction in which a substance rotates the plane of polarized light. Dextrorotatory substances rotate the light in a clockwise direction, while laevorotatory substances rotate it in a counterclockwise direction.
3. What is the angle of rotation?
Ans. The angle of rotation is the measure of the amount by which a substance rotates the plane of polarized light. It is usually expressed in degrees and can be either positive or negative, depending on the direction of rotation.
4. What is specific rotation?
Ans. Specific rotation is a characteristic property of a substance, which is a measure of its ability to rotate the plane of polarized light. It is defined as the angle of rotation produced by a pure substance at a specific concentration, temperature, and wavelength of light.
5. How is optical activity determined experimentally?
Ans. Optical activity can be determined experimentally by using a polarimeter. A polarimeter measures the angle of rotation produced by a substance when polarized light passes through it. The specific rotation of the substance can then be calculated using the formula specific rotation = observed rotation / (concentration x path length).
