What is enantiomers, racemisation, and chirality

Posted by Manpreet Singh 8 years ago

CBSE > Class 12 > Chemistry

2 answers

Tushar Sharma 8 years ago

In chemistry, racemization is the conversion of an enantiomerically pure mixture (one where only one enantiomer is present) into a mixture where more than one of the enantiomers are present.

0Thank You

Tushar Sharma 8 years ago

each of a pair of molecules that are mirror images of each other is called enantiomers. Racemisation is a conversion, by heat or by chemical reaction, of an optically active compound into an optically inactive form which half of the optically active substance becomes its miror image (enantiomer). Chirality is a geometric property of some molecules and ions. A chiral molecule/ion is non-superimposable on its mirror image.
