Question

These molecules are _____.

-R-dopa and L-dopa
- structural isomers
-geometric isomers
- thiols
-enantiomers

Answer 1

Enantiomers are molecules that share the same chemical structure but have different three-dimensional arrangements of atoms. D-alanine and L-alanine are examples of enantiomers.

Step-by-step explanation:

Enantiomers are molecules that share the same chemical structure and chemical bonds but differ in the three-dimensional placement of atoms so that they are mirror images. For example, the amino acid alanine has two enantiomers, D-alanine and L-alanine.
