Expert Solution
Step 1

The carbons have the valency of 4 when these valencies are satisfied by different substituents, that carbon is known as the chiral carbon.

This chiral carbon is also known as the stereogenic centre. In this stereogenic centre, the substituents are numbered based on their priority and then if the substituents are seen numbered in the clockwise direction, then that carbon has the configuration of R. If the numberings are seen in the anticlockwise direction, then that carbon has the configuration of S.

Enantiomers are non-superimposable mirror images of the chemical compound. 

 

Step 2

In the given structure:

The absolute configurations of the stereogenic centres can be given as:
