Optically Active Compounds
Those compounds which rotate the PPL light in either clockwise direction or in anticlockwise direction are called optically Active Compounds.
Dextorotatory and laevorotatory Compounds are optically Active in nature.
compunds which doesn not rotate PPL are optically inactive in nature.
Assymetric Carbon (chiral carbon)
Sp³ hybridised carbon attached with four different substituent are known as chiral carbon.
Chiral
Those object's whose mirror images are not super imposible on each other are called as chiral.
Enentiomers
These are those sterioisomer whose mirror images are non superimosible on each other.
Like Above molecule 1 and molecule 3 are enentiomers of each other.
Disterioisomer
These are those sterioisomer which are not mirror images of each other.
Racemic Mixture
A mixture containing two enentiomers in equal proportion called as racemic mixture.
It is denoted by (dl) or _+.
This process is known as racemisation.
In Racemic Mixture
- If A is the only product formed in the reaction then A is called as retention.
- If B is the only product formed in the reaction then the B product is known as inversion.
- A and B both are formed in the reaction in equal proportions then it is called as racemic mixture and process known as racemisation.
- Racemic mature is optically inactive in nature as isomer rotate the PPL in direction opposite to another.
