Enantiomers are only associated with amino acids. are always designated either d or l. can exist for molecules with more than one chiral carbon. can be specific types of diastereomers.

can exist for molecules with more than one chiral carbon

Explanation:

Stereoisomers are the molecules that have same composition but have different spatial arrangement ,

A chiral is any object that is non superimposable on its own mirror image .

Chiral center is any carbon with tetrahedral geometry and with 4 different substituents .

The chiral structures which cannot be superimposed but are mirror images are known as an Enatiomers .

If they are not mirror images then they are called diastereomers .

Enatiomers can be denoted by , +/- sign , D or L and R or S .

They can have more than one chiral center .

Hence from the question , the correct option is can exist for molecules with more than one chiral carbon .

it's c. elements are placed in rows based on how may valencies electrons have.

they are made of gases.

they have a spherical shape.

they make energy through fusion.
