Question

Discuss the optical isomerism of lactic acid.

Answer 1

Answer:

Optical isomers. The asymmetric carbon atom in lactic acid has four different groups attached: –CH3, –H, –OH and –COOH. The two molecules are mirror images of one another and are chiral – they differ in the same way that left and right hands differ.

Optical isomers are two compounds which contain the same number and kinds of atoms, and bonds (i.e., the connectivity between atoms is the same), and different spatial arrangements of the atoms, but which have non-superimposable mirror images. Each non-superimposable mirror image structure is called an enantiomer.
