Define Racemic mixture

Explanation

Racemic mixture : Equal portions of Enantiomers combined to form an optically inactive mixture . This mixture is called racemic mixture .
1) Here rotation due to one isomer will be exaclty cancelled by the rotation of due to other isomer .
2) The process of conversion of enantiomer into a racemic mixture is called as racemisation .
Eg : (+)` Butan-underset("Enantiomers")(-2-ol + (-) Butan)2-ol to (pm) underset("Racemic mixture")(Butan-2-ol)`
