About This Presentation

optical ismoers are those which different behavoiurs towards the plane polarized light. they don't show any behaviour towards ordinary light but behaves differently to PPL. In order to be optically isomer the carbon must contain chiral bond.


Slide Content

Optical Isomers  Then what's different? Same Molecular Formula Same Physical and Chemical Property Same Structural Formula As it's type says optical ; the compounds differ in the behaviour towards Light

Do optical isomers behaves toward all types of light? No, They only behaves toward PPL(Plane Polarized Light) Ordinary Light Polarizer 

Type of compound on the basis of Optics Optically Active Compounds :- Optically Inactive Compounds:- Compounds which have the ability to rotate plane polarized light . Example :-   Glyceraldehyde ( C₃H₆O₃), Glucose( C₆H₁₂O₆) How is optically active compounds detected? Using Polarimeter. Conducting Experiment in Lab. Compounds which   don't have the ability to rotate plane polarized light. ​ Example :- ​ 2-chloropropanal   ( C₃H₅ClO )

Optically Active compounds Dextrorotatory Levorotatory Why do optically active compounds bends Light? Optical activity occurs when these chiral molecules interact with polarized light. NOTE:- For being optically active the compound must be  chiral compound. Chiral compound means the compound in which carbon is bonded with different groups.

Dextrorotatory (d-form): The compound rotates the plane of polarized light in a clockwise direction (to the right) PPL rotates in clockwise direction or Right side It is denoted by d or + sign

Example of Dextrorotatory Last group is in right side so it's dextrorotatory       D(+) Glucose
